Activate 1 of these effects (but you can only use each effect of "Volcanic Emission" once per turn);
• Take 1 "Volcanic" monster from your Deck, and either add it to your hand or Special Summon it, ignoring its Summoning conditions, but return it to the hand during the End Phase.
• Target 1 Pyro monster on the field; inflict damage to your opponent equal to that monster's original ATK, or if you targeted a monster you control, the damage is halved.
