Seas of Molten Rock

When Seas of Molten Rock enters the battlefield, create a 5/5 blue Lavawhale token with protection
from red.
If a land would produce {u}, it produces {r} instead.
Our instruments read calm seas. Suddenly, the
very water cracked and boiled, setting the ship
aflame! I was lucky to survive.
