Game plan

  1. Hit its Weakness. Regice ex is weak to Metal, so those attacks do double damage. 39 Standard cards can Knock it Out in one hit that way — the fastest needs just 0 Energy.
  2. Win the Prize trade. It gives up 2 Prize cards when Knocked Out. 40 single-Prize Pokémon can take it out in one attack, so you trade 1 Prize for 2.
  3. Plan for its big hit. Its strongest printed attack is Ice Prison for 140 (4 Energy). 331 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.
