When this card is activated: You can place 1 or 2 Dinomist Pendulum Monster(s) from your Deck in your Pendulum Zone, but you cannot Pendulum Summon monsters until the end of the next turn, except Dinomist monsters (even if this card leaves the field). Once per turn, if this card is already face-up in your Spell & Trap Zone: You can Tribute 1 Dinomist monster, then target 1 card your opponent controls; return it to the hand.
