Skyward Atoll

If you control two or more other lands, “Skyward Atoll”
enters the battlefield tapped.

{t}: Add {u}.

{2}{u}: Skyward Atoll becomes a 3/2 blue Shark creature
with flying and menace until end of turn. It’s still a land.

Whenever Skyward Atoll deals combat damage to a player
create a Blood token or Treasure token.
