Game plan
- Hit its Weakness. Mega Meganium ex is weak to Fire, so those attacks do double damage. 20 Standard cards can Knock it Out in one hit that way — the fastest needs just 1 Energy.
- Win the Prize trade. It gives up 3 Prize cards when Knocked Out. 8 single-Prize Pokémon can take it out in one attack, so you trade 1 Prize for 3.
- Plan for its big hit. Its strongest printed attack is Giant Bouquet for 70+ (3 Energy). 1,144 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.
