Ozolk, Archon of Floods

As long as this spell is cast, it isnt a creature.
Emerge: {1}{b/g}{b/g}{u}{u}
You may cast Ozolk from your graveyard by using its emergence cost.
When this spell is cast, for each player, put
a flood counter on a land they control.
When Ozolk enters the battlefield, each player who no lands without flood counters loses the game.
