Kanto League

When Kanto League enters the battlefield, each
player exiles the top six cards of their library face
down.
If a creature deals lethal damage in a fight, their controller returns one card exiled by Kanto
League to their hand. Whenever a player has no
such cards in exile, they win the game.
{0}: Target creature you control fights target
creature you don't control. Any player may
activate this ability as a sorcery once each turn.
