Rare

{1}{R}{R}

Snow Sorcery

Tundra Fumarole deals 4 damage to target creature or planeswalker. Add {C} for each {S} spent to cast this spell. Until end of turn, you don't lose this mana as steps and phases end. ({S} is mana from a snow source.)

The only thing that smells worse than troll is burnt troll.
