Win the Prize trade. It gives up 3 Prize cards when Knocked Out. Attack it with single-Prize Pokémon so each trade puts you ahead.
Plan for its big hit. Its strongest printed attack is Illusory Impulse for 300 (3 Energy). 62 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
