A PvP Analysis on Icy Wind Thievul (August 2026 Community Day)

This month’s Community Day is quietly a really good one for PvPers, and even better than I think most are giving it credit for! Come see why THIEVUL suddenly emerges as a Top 50 PvP Pokémon, and why even THAT may be ranked too low… after we kick it off with our Bottom Line Up Front:

B.L.U.F.

• Unlike many of the most successful Dark Pokémon, Thievul is decidedly NOT bulky, but it’s found decent success in PvP anyway thanks to really good, spammy Dark damage and a decent coverage move with closing power.
• Post-Community Day, Thievul emerges with a move that provides new coverage and helps bulk it up a bit (in a roundabout way, at least).
• PvPoke, as wonderful as it is, currently has Thievul ranked with what I believe is an unideal moveset. So even though it already shoots up to a Top 50 Pokémon, I think it should actually be even higher… and I’ll show you why!
• Thievul still ranks rather unimpressively in Ultra League and most may still be ignoring it there… but quietly, swapping around charge moves grants it double digit new wins that should have it ranked much, much higher there as well. It should be a very legit option even in Open UL play now! And again, I’ll show you why….

Intrigued yet? Good, then let’s get into the details!

THIEVUL Stats and Moves

Thievul Dark

Great League Stats

• (Highest Stat Product IVs: 0-15-11, 1499 CP, Level 27)

Ultra League Stats

• (Assuming 15-15-15 IVs; 2415 CP at Level 50 / 2444 CP at Level 51)

So, mono-Dark means weaknesses to Fighting, Fairy, and Bug damage, a resistance to Ghost and Dark damage, and a double resistance to Psychic damage. I think most people have a feel for this particular typing by now (though the Bug weakness often seems to surprise people).

The thing I want to talk about instead is the stats. Dark is a typing that I think generally has bulk in PvP, with the best Dark types being things like Mandibuzz, Guzzlord, Umbreon of course, and even some things you see in Cups but not so much in Open formats like Obstagoon, Alolan Raticate, and Scrafty. And heck, even other big names like Galarian Moltres are bulky enough. But Thievul is quite different, with bulk that is, frankly, pretty poor. For a few examples:

• Thievul has more bulk than Hisuian Qwilfish and Skuntank, but trails both Alolan Muk and Drapion. In Great League, it trails Malamar, Zweilous, and Sableye, and is basically tied with Spiritomb, and ahead of stuff like Mightyena and Morgrem.
• In Ultra League, Thievul has less bulk than Incineroar, Kingambit, Bombirdier, and even Tyranitar. (Though in fairness, it can’t quite reach 2500 CP, which holds its bulk back.)
• Among non-Dark types, Thievul’s bulk is in the same territory as stuff like Skeledirge, Talonflame, and Piloswine in Great League, and sandwiched between Nidoking and Bewear above it and then Gyarados and Tsareena below it in Ultra League.

I know what you’re thinking… none of these things I’ve just listed here are known for their bulk. And you’re right… so neither is Thievul! I wouldn’t quite call it a true “glass cannon”, but it’s closer to that label than it will ever be any “bulky” label.

Many of you have probably been following me long enough to know what I’m going to say next, but I’m gonna say it anyway for those in the back. 😅 Bulk is a major factor in a Pokémon’s PvP success, but not the “be-all and end-all”. (TIL I learned that’s originally from Macbeth, by the way… thanks for another one, Mr. Shakespeare!) There are plenty of squishy Pokémon that find great success in PvP anyway… and thanks to its moveset, Thievul is among them! Let’s check it out.

Fast Moves

• Sucker Punch – Dark type, 4.0 DPT, 3.5 EPT, 1.0 CoolDown
• Snarl – Dark type, 1.67 DPT, 4.33 EPT, 1.5 CD
• Quick Attack – Normal type, 2.5 DPT, 4.0 EPT, 1.0 CD

This is now my third spotlight article on Thievul, and it’s all Sucker Punch‘s fault. When it was first released, Thievul came with only Snarl and Quick Attack, two decent fast moves, but not ones that drove Thievul to success. But then Niantic stealthily added a new fast move to its repertoire with Sucker Punch, and the immediate improvement was so significant that a whole new analysis article was needed. Nothing about this is changing this Community Day, but I wanted to highlight how much of Thievul’s success is driven by the sheer awesomeness of Sucker Punch.

But now what you’re really here for….

ᴱ – Exclusive (Community Day) Move

Charge Moves

• Night Slash – Dark type, 50 damage, 35 energy, 12.5% Chance: Raise User Attack +1 Stage
• Icy Windᴱ – Ice type, 60 damage, 45 energy, Reduces Opponent Attack -1 Stage
• Play Rough – Fairy type, 90 damage, 60 energy

That’s right: for most of its history in GO, Thievul has been that super-rare Pokémon with more fast move options (three) than charge moves (two). Is there any other fully evolved Pokémon in the game like that? 🤔 (“Kowalski! Analysis!”) Night Slash is a little underwhelming these days, but a 35-energy move is still a 35-energy move, cheapest in the game and great for pressuring shields and setting up a closer.

In this case, that closer is also a little underwhelming, but viable… it just feels bad throwing Play Rough when you know that there are multiple better Fairy moves out there, including Moonblast which deals 20 more damage for the same energy cost.

Still, combined with high pressure from Sucker Punch, Night Slash/Play Rough works out fine, as we’ve already highlghted. Fairy nicely fills Dark gaps against Fighting and Dark types, and leaves Thievul with very few opponents that don’t have to worry about throwing a shield or two at it.

But now we have a new alternative, and it might be just what Thievul needed to be fully unleashed. Night Slash is cheap, but rather superfluous with Sucker Punch dealing plenty of Dark-type damage on its own. So why not some coverage instead? Enter Community Day move Icy Wind. It’s obviously not as cheap as Night Slash, but still inexpensive enough to keep up the shield pressure without too much trouble. But the slower pacing almost doesn’t matter with what else it brings to the table.

First is the obvious coverage; again, there’s not too much that can shrug off Dark and Fairy damage, but what’s out there that does (Poison/Fairy Galarian Weezing comes immediately to mind) cannot also resist Ice damage. Really though, Ice is more interesting for the additional super effective damage that comes with it, which immediately translates to new wins that start popping up like Stunfisk, Diggersby, Clodsire, Cradily, and Jumpluff. None of them are particularly weak to Dark or Fairy damage, but they ARE all weak to Ice, so Thievul now beats them. It’s as simple as that!

The real bonus, however, is Icy Wind’s famous debuffing effect. Reducing the opponent’s Attack strength is just what the doctor ordered for something flimsy like Thievul, allowing it to hang in battles longer and outlast things that it couldn’t before. While the new wins I just listed are rather obvious, other new wins you’ll see like Kingdra, Qusgsire, and Mimikyu are not so obvious… they aren’t notably weaker to Ice than they are to Thievul’s other moves. (Well, Mimikyu does resist its Dark damage, but stick with me here.) Thievul gains the ability to overcome them just by hanging in the fight longer. Also simple, right?

And so it goes for Thievul. There ARE a couple former wins that can slip away when you replace Night Slash with Icy Wind due to less charge moves being thrown or, more commonly, because that extra bit of Night Slash damage is needed to outrace things. (Or Ice is heavily resisted, such as the case of Dewgong which Night Slash can finish off while Icy Wind is more liability than help.) But for the most part, this is a major boon to its prospects that translates directly into clear-cut new wins, and in bunches. Let’s dive into the sims and see just HOW much better Thievul is now!

GREAT LEAGUE

Now I mentioned earlier that PvPoke is currently ranking (and default simming) Thievul with what I believe is the “wrong” moveset. I get why the site has defaulted to Night Slash/Icy Wind, as Icy Wind appears in many ways as a big upgrade on Play Rough… significantly cheaper as a coverage move while bringing that sweet, sweet opponent debuff to extend Thievul’s lifespan in battle. Mr. PvPoke and I agree across the board at least 95% of the time… but I must voice my disagreement in this case.

My hypothesis earlier is that Night Slash is a little redundant now that Thievul has TWO other charge moves that both bring a lot to the table in terms of coverage and overall impact. Night Slash spam is great, and its 12.5% buff chance going off can absolutely win you battles you won’t win otherwise. I will NOT say PvPoke is out-and-out wrong pr that players that follow that advice and run Night Slash/Icy Wind are foolish. I just think they’re tying a hand behind their back.

As great as Thievul’s high-pressure Dark damage is, a good amount of its success is owed to Play Rough. The impact of having that hard an answer to Fighters that otherwise pick it apart and opposing Darks that are always lurking out there — and the fact that both of those typings severely blunt Sucker Punch and Night Slash — cannot be overstated.

You know how Mandibuzz and Umbreon are great, especially in Dark-heavy Cup formats, not just because of their spammy Dark moves (and bulk), but also because they have moves that hit back at things that resist Dark damage with neutral coverage (Aerial Ace for Mandi and Last Resort for Umbry)? Take that and turn it into battle-changing super effective damage and you have Thievul with its Play Rough.

To make it clearer, while Night Slash/Icy Wind does have a better record than Night Slash/Play Rough, it’s only +3 wins overall, with Medicham and Quagsire moving into the win column while Ice damage brings in new wins over a list of Ice-weak things I mentioned earlier: Stunfisk, Diggersby, Clodsire, Cradily, and Jumpluff. Nice, and that alone would make this Community Day worth it. But Thievul can do BETTER if you keep Play Rough.

Because Icy Wind/Play Rough is where it’s at, folks. The lack of Night Slash pressure does mean losses to Lickilicky and Ice-resistant Dewgong, but look at the gains: Medicham and Quagsire are back in the win column, along with Shadow Quag for the first time, Kingdra, and Mimikyu.

The overall results are pretty close with shields down when you compare all three movesets, not too surprisingly. But in 2v2 shielding, Icy Wind and its debuffing again has obvious advantages over Thievul’s former best. Paired with Night Slash, Icy Wind does drop Charjabug, the mirror, and a former win versus Lickilicky drops to a tie now, but the new wins outweigh that: Jumpluff, Mantine, Quagsire, Medicham, and Guzzlord. Not bad!

However, once again, Play Rough/Icy Wind is better, picking up those same five wins PLUS Cradily and Corviknight. To be fair, that move combo also shows unique wins over Clodsire and Empoleon, but it’s really Icy Wind that on its own conquers both of them. And again to be fair, Talonflame gains a couple of potential outs in 2v2 shielding without Night Slash spam… Thievul still has the advantage, but it’s worth pointing out that a Flame Charge/Fly Talon gains a new path to potential victory.

So again, Night Slash/Icy Wind is fine, and would be worth the Community Day grind. But JRE recommends Play Rough’s closing power and coverage paired with Icy Wind instead. How do YOU feel about that? Sound off in comments… I’d love to see some discussion on this.

And to throw more fuel on that fire, let’s check out a place where Thievul has NOT had much success to this point: Ultra League. It tops out at 2415 CP at best (or 2444 CP if you best buddy it and push to Level 51), but honestly, it hasn’t been worth it. If you’re going to make THAT kind of commitment, at least get the bang for your buck with something like Umbreon, amirite? Well, strap yourselves in, boys and girls… that may be about to all change!

ULTRA LEAGUE

So clearly Icy Wind is worth having in Great League, with enough new wins that you may need to use two hands to count them all. Now in Ultra, the extra Dark damage of spammy Night Slash still has its uses, particularly against targets that resist Ice and Fairy damage (and therefore outlast Icy Wind/Play Rough Thievul, like Forretress and Typhlosion), but there’s just too much that Ice (and debuffs) can do in this meta to ignore.

There’s the obvious weak-to-Ice stuff like Zygarde, Regidrago, Toucannon, and Galarian Moltres, some that aren’t as immediately obvious but lose in large part due to neutral debuffs (Lickilicky, Corviknight, Bellibolt. Shadow Ampharos, Swampert, Steelix), and then ones that make NO sense, like Blastoise (resists Icy Wind), Tentacruel (resists Ice and Fairy), and my favorite head-scratcher here: Shadow Empoleon, which resists Play Rough and double resists Icy Wind.

Yet it is Ice (and Fairy) that beats it, while neutral and spammy Night Slash loses, either in combinatoon with Icy Wind or just trying to outspam on its own. That attack debuff from Icy Wind is legit even when the move itself is hitting like a soft pillow. And Play Rough is critical too… without its closing power, you may miss Icy’s improvements entirely!

While shieldless matchups are once again not much improved as compared to pre-Icy Wind (though worth noting that a Level 51 Thievul can actually pick up additional wins over Corviknight and Drapion), the improvement in 2v2 shielding is not quite as mind-blowing at the 1v1 improvements (seriously, double digit new wins still has my jaw on the floor a bit), but the improvement over the former best is still very apparent.

Only Shadow Ampharos and Steelix slip away, while all the following slide into the win column: Drapion, Shadow Empoleon, Forretress, Shadow Ninetales, Regidrago, Zygarde, Swampert, and non-Shadow Ampharos, a +6 improvement overall. Like, what are you waiting for? This combined with the 1shield improvement makes this a no-brainer. You will likely NEVER have a better chance to grind for the XLs you need, so go go go!

IN SUMMATION

Usually, a Community Day comes along that you expect to be really good — or bad — and while I try to always cover them regardless, yeah, the end result is usually a confirmation of everyone’s expectations. But every now and then, one arrives quietly, blowing in like a gentle (icy?) wind and passing right on by if you’re not paying attention. This is one of those, with the potential to blow in like a hurricane in PvP metas.

Seriously, Thievul’s new rankings seem low to me, and that’s with it nearly cracking the Top 40 in Great League! Yeah… it’s better than even that, folks! And worth the full grind for Ultra League as well, with all 296 XL Candy needed to max it out. It’s actually, really, truly worth it if you have the fortitude to brave that late summer weather.

Whether you plan to give it your all this Community Day or take it easy and settle on just a new Great League Thievul and maybe a couple shinies, I wish you good weather and happy hunting! Until next time, you can usually find me on Twitter with regular GO analysis nuggets or Patreon.

Good luck on your grind, have some fun with your locals, and catch you next time, Pokéfriends!
