Game plan

Hit its Weakness. Cynthia's Garchomp ex is weak to Grass, so those attacks do double damage. 9 Standard cards can Knock it Out in one hit that way — the fastest needs just 1 Energy.
Win the Prize trade. It gives up 2 Prize cards when Knocked Out. 3 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 Draconic Buster for 260 (2 Energy). 94 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
