Mutavault

Volcanic Geyser deals X damage to any target.

(T: Add G.)

Enchant creature When this Aura enters, tap enchanted creature. Enchanted creature doesn't untap during its controller's untap step.

Put a +1/+1 counter on target creature you control. Then that creature fights target creature you don't control. (Each deals damage equal to its power to the other.)

Whenever a player taps a nonbasic land for mana, this enchantment deals 1 damage to that player.

Target creature you control gets +1/+1 and gains hexproof until end of turn. (It can't be the target of spells or abilities your opponents control.)

Enchant Equipment At the beginning of your upkeep, if enchanted Equipment is attached to a creature, destroy that creature.
