Game plan

  1. Hit its Weakness. Mega Kangaskhan ex is weak to Fighting, so those attacks do double damage. 30 Standard cards can Knock it Out in one hit that way — the fastest needs just 1 Energy.
  2. Win the Prize trade. It gives up 3 Prize cards when Knocked Out. 19 single-Prize Pokémon can take it out in one attack, so you trade 1 Prize for 3.
  3. Plan for its big hit. Its strongest printed attack is Rapid-Fire Combo for 200+ (3 Energy). 187 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
  4. Watch the Retreat Cost. It costs 3 Energy to retreat. If it gets stuck in the Active Spot, that's your chance.

One-hit Knock Outs using Weakness

These Fighting attacks do at least 300 after Weakness. Fastest (fewest Energy) first.
