Hoopa

Hoopa is a potent wallbreaker with a good offensive Psychic / Ghost typing and an enormous movepool. Possessing the highest Special Attack stat in RU, Hoopa is a fearsome Pokemon, with coverage moves such as Hyperspace Hole, Shadow Ball, and Focus Blast. Hoopa's Special Defense paired with its Ghost typing allows it to be an effective spinblocker against the primary Rapid Spin user in the tier, Blastoise. Unfortunately, Hoopa is particularly lacking in Speed and Defense and therefore should be switched in very carefully against strong physical attackers. Its typing may be useful offensively, but it makes it 4x weak to Dark- and Ghost-type moves. Pursuit trappers are a challenge for Hoopa, as they have a high chance to OHKO it even if it does not switch out. Furthermore, Hoopa should be wary of Pokemon like Meloetta, as they are known to carry Shadow Ball as coverage.
