Win the Prize trade. It gives up 2 Prize cards when Knocked Out. 15 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 Moss Agate for 230 (3 Energy). 125 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
Watch the Retreat Cost. It costs 2 Energy to retreat. If it gets stuck in the Active Spot, that's your chance.
