"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.
|Pack||Cybernetic Rebellion [SR]|
Alien Ammonite is a requirement to summon Cosmic Fortress Gol’gar. Luckily Alien Ammonite’s effect makes this easy by Special Summoning the non-Tuner monster you need to Synchro Summon. Special Summon a level-4 Alien with Alien Ammonite’s effect.
Cosmic Fortress Gol’gar can only destroy your opponent’s cards if you have A-counters to spend so here are some cards you can use to Spread A-counters on the field.
You can return Brainwashing Beam to your hand to later reuse it. But this will return the opponent’s monster back to their side of the field.
