Blissey is the evolution of Chansey and the uncontested queen of special walls. With 255 base HP and 135 base Special Defense, Blissey soaks special hits that would obliterate any other Pokemon in the game. Every serious stall team in OU runs her.
Base Stats
Blissey has 255 HP, 10 Attack, 10 Defense, 75 Sp.Atk, 135 Sp.Def, and 55 Speed. That 10 Attack/Defense is the lowest in the game for a non-Happiny family Pokemon — Blissey\'s physical defense is literally nothing. But her special walls are beyond legendary.
Natural Cure Ability
Natural Cure removes any status condition when Blissey switches out. This lets her absorb Toxic, Burn, and Paralysis, then switch out free of any lingering effect. It\'s the perfect ability for a switching wall.
Wish Support Role
Blissey\'s signature move is often Wish — it places a delayed heal that triggers on the next turn, giving allies 50% HP recovery. A Blissey on your team is effectively a passive Pokemon Center: she can keep every teammate healed all match.
Best Moveset
Seismic Toss, Wish, Protect, Soft-Boiled. Seismic Toss deals flat damage equal to Blissey\'s level, bypassing her terrible Attack stat. Protect ensures Wish heals connect. Soft-Boiled is a self-heal for 50% HP.
Counters
Physical attackers eat Blissey for breakfast — Machamp, Urshifu, and Tyranitar demolish her in one hit. Taunt users stop her from setting up Wish. Trick users can replace her item with a useless Choice Scarf.
