Guide and event priorities

Although Week #1 is arguably the least exciting Ultra Bonus Week, there’s still a few noteworthy things that will keep things interesting. Shiny hunting is the name of the game, so be sure to check out Liam’s great Shiny Hunting Methods In Pokemon Go – Part 1 article.

Top priority

  1. Catching new shiny Pokemon: Sentret and Gligar. Sentret and Gligar are the two new event shinies and they should be easier to obtain during the event than after it. Sentret is a common spawn everywhere, but Gligar could be a bit tricky. We suggest shiny checking every single one. Furret is surprisingly hard opponent in Trainer Battles.
  2. Maximizing incubator usage. As incubator effectiveness will be doubled during the event, we advise that you keep the free Incubator active as much as possible. With Adventure Sync (make sure it’s turned on!) and a fair bit of walking, you should net a hefty amount of Stardust from hatches alone.
  3. Farm Raikou candy. Believe it or not, Raikou is one of the strongest Electric types to date, and will likely stay that way for years to come. With Entei and Suicune being lower tier attackers – there are much better Fire and Water types out there – Raikou is the only one worth raiding. Johto Beasts can be shiny, which is also a plus!
  4. Collect Unown letters: ULTRA. It goes without saying, but still – if you can, hatch as many 10 KM eggs as you can. Unown are always good trade value, especially at GO Fest and Safari Zone events, where people will trade you insane Pokemon for a missing Unown letter.
  5. Fill your Johto Pokedex gaps. Although most of our readers have completed their Johto Pokedex months (and years) ago, we’re sure that there’s someone out there who has at least one shadow in this section. Fix that!

Notable Johto Pokemon to keep an eye out for

The following Pokemon from the Johto region are considered good catches for PvP or PvE, be sure to catch a few if possible:

Pokemon GO MarillMarill

Azumarill is disgustingly strong in the Great League, so every Marill you catch ahs the potential to become a menace. Look for good PvP IVs and don’t think twice.

Pokemon GO PinecoPineco

Pineco’s evolution – Forretress – is one of the strongest Pokemon in the Great League, as it has been blessed with the fabled Steel typing. Be sure to get a few while the event lasts, they’re a PvP staple.

Pokemon GO SneaselSneasel

Evolves into Weavile, a high DPS Dark and Ice typed glass cannon. Good for some raids, occasionally fun to fight against.

Pokemon GO SlugmaSlugma

The boring fiery snail lives on as Magcargo in the Great League, where it counters Forretress and Fire types surprisingly well. Weird typing, niche usage.

Pokemon GO SwinubSwinub

Swinub evolves into Piloswine and Mamoswine, the best Ice type we currently have in Pokemon GO. Mamoswine is absurdly strong, make sure to farm up on Swinub candy if you can.

Pokemon GO SkarmorySkarmory

Flying Steel Great League problem. Get a good one, spend some dust on it, save it and cherish it. Skarmory is ranked as #5 best Pokemon in the Great League by PvPoke.com. That’s quite good for one of the worst PvE Pokemon from the Johto region (Shuckle not included)!

Pokemon GO LarvitarLarvitar

There’s no such thing as “I have enough Larvitar candy”. Tyranitar is one of the most versatile Pokemon ever to be added in Pokemon GO, and farming Larvitar candy is the only viable route to grind your way to a Tyranitar army. Don’t skip!
