Rayquaza

Flip a coin. If tails, this attack does nothing. If heads, prevent all effects of attacks, including damage, done to this Pokémon during your opponent's next turn.

コインを1回投げウラなら、このワザは失敗。オモテなら、次の相手の番、このポケモンはワザのダメージや効果を受けない。

Flip a coin until you get tails. This attack does 20 more damage for each heads.

ウラが出るまでコインを投げ、オモテの数×20ダメージを追加。
