Win the Prize trade. It gives up 2 Prize cards when Knocked Out. 17 single-Prize Pokémon can take it out in one attack, so you trade 1 Prize for 2.
Plan for its big hit. Its strongest printed attack is Aura Knuckle for 120 (3 Energy). 570 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
