Abilities, attacks, weakness & resistance
If your opponent has any evolved Pokémon in play, choose 1 of them and flip a coin. If heads, your opponent takes the highest Stage Evolution card on that Pokémon and shuffles it into his or her deck.
During your opponent's next turn, the Defending Pokémon can't evolve except from effects of attacks or Pokémon Powers. (Benching that Pokémon ends this effect.)
Other cards from 闇、そして光へ... (Darkness, and to Light...)
Dark Omastar (neo4_ja-38) is a Water-type Stage 2 Pokémon from the 闇、そして光へ... expansion printed as a Normal rare. Its Prehistoric Water attack can target an opponent's evolved Pokémon and, on a successful coin flip, force the highest Stage Evolution card on that Pokémon to be returned to the opponent's deck, while Dark Tentacle deals 30 damage and prevents the Defending Pokémon from evolving on the next turn except by effects.
