Hey Trainers,

Unovan Yamask will be a Ghost type T1 raid boss during the Halloween 2021 event. Unovan Yamask evolves into Cofagrigus.

Yamask

Yamask shouldn’t be that difficult to beat, since it’s only a T1 raid. Practically any player can beat it with decently levelled Pokemon. It does have a little bulk, so try not to use any types Yamask resists.

It’s a Ghost type, so it’s weak to Dark and Ghost types. It’s resistant to Bug and Poison types, and it has 2 large resistances being Normal and Fighting.

Top Counters

Shadows and Megas won’t be listed. They’re not necessary to take down a T1 in good time, and Shadow Pokémon are incredibly expensive to power up. However, if you have any of the listed Pokémon as shadow forms, they’re of course better.

Dark types utterly wall Yamask, so they’re great options.

Conclusion

Yamask only comes around for a portion of the year, and thanks to Cofagrigus getting Shadow Claw recently it has skyrocketed into PvP relevancy. Best to get a good one while you can, and try to get as much XL candy for Ultra League as possible.

Stay safe, trainers!
