The Kyogre Legendary card was first introduced in the EX Ruby & Sapphire expansion in 2003, and its been making waves ever since
Thats good, but it also reads, Whenever you cast a spell, each opponent reveals cards from the top of their library until they reveal a land card, then puts those cards into their graveyard.

Oh, its your end phase
