During your Main Phase: You can destroy 1 Dinosaur monster you control, and if you do, Special Summon 1 "Jurrac" monster from your Deck. If your opponent Special Summons a monster(s) and they activated monster effects 4 or more times this turn (except during the Damage Step): You can Special Summon 1 "Jurrac Meteor" from your Extra Deck. (This is treated as a Synchro Summon.) If a "Jurrac" monster(s) you control would be destroyed by card effect, you can banish 1 Dinosaur monster from your GY instead. You can only use each effect of "Jurrac Volcano" once per turn.
