Its attack, Psy Purge , is nice thanks to its versatility by simple two psychic energies, and can be accelerated easily between turns or Pokmon that support it, such as Cresselia CRE 64 or Shadow Rider Calyrex VMAX CRE 75, it can discard up to 3 Energy from your Pokmon, which is 90 damage for each Energy discarded in the process

Additionally, its Topaz Bolt attack deals 300 damage, which is enough to knock out any Pokmon in the game
