Card effect (current official text)"Alien Ammonite" + 1 or more non-Tuner "Alien" monsters
Once per turn, you can select any number of face-up Spell or Trap Cards. Return those cards to their owners' hands, and distribute new A-Counters among monsters on the field equal to the number of cards returned. Once per turn, you can remove 2 A-Counters from anywhere on the field to destroy 1 card your opponent controls.
Rulings
- If 3 cards are returned, you can: place 1 Counter on 3 different monsters, or place 1 Counter on 1 monster and 2 Counters on a different monster, or place all 3 on 1 monster.
- If a card is not returned to the hand (maybe it was destroyed), no counter is placed for that card.
