Walrein (sm12-52) is a Water-type Stage 2 Pokémon from the Cosmic Eclipse set. Its Cold Snap attack for one Water energy prevents the opponent from playing Trainer cards from hand on their next turn but is locked out if any of your Pokémon used that attack on the previous turn, and its Blizzard attack deals 120 damage while also dealing 10 damage to each of your opponent's Benched Pokémon. With a ×2 Metal weakness and a four-cost retreat, it functions as a heavy-hitting, high-retreat attacker that can apply spread damage to disrupt Bench-based strategies.
