If a red source you control would deal damage to an opponent or a permanent an opponent controls, it deals that much damage plus 2 instead.

At the beginning of each player's upkeep, Sulfuric Vortex deals 2 damage to that player. If a player would gain life, that player gains no life instead.

+2: Search your library for a basic Mountain card, reveal it, put it into your hand, then shuffle. −3: Koth, Fire of Resistance deals damage to target creature equal to the number of Mountains you control. −7: You get an emblem with "Whenever a Mountain enters the battlefield under your control, this emblem deals 4 damage to any target."
