Game plan
- Hit its Weakness. Yanmega ex is weak to Lightning, so those attacks do double damage. 32 Standard cards can Knock it Out in one hit that way — the fastest needs just 2 Energy.
- Win the Prize trade. It gives up 2 Prize cards when Knocked Out. 18 single-Prize Pokémon can take it out in one attack, so you trade 1 Prize for 2.
- Avoid Fighting attacks. Yanmega ex resists them, so they do less damage.
- Plan for its big hit. Its strongest printed attack is Jet Cyclone for 210 (4 Energy). 154 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
- Watch the Retreat Cost. It costs 1 Energy to retreat. If it gets stuck in the Active Spot, that's your chance.
