Introduction to Aliens


Aliens is a deck that uses A-Counters: These counters are used to activate card effects from monsters, traps and spells. Some Aliens are able to use A-counters to reduce enemy monsters attack and defense, and will have the text "If a monster with an A-Counter battles an Alien monster, it loses 300 ATK and DEF for each A-Counter during damage calculation only." Alien decks are extremely versitile and have room for situational tech cards, making them a strong deck for experienced players as well.

Extra Information

  • Aliens' A-counter -300 ATK effect stacks, so 2 Aliens (with the text effect) = -600 ATK with 1 counter.
  • Play "A" Cell Recombination Device on the End Phase of your opponent’s turn; this way you can get the effect of adding an Alien monster to your hand on your following turn.
  • Alien Kid's effect to place an A-counter cannot be negated by Divine Wrath.
  • ECon-taking an enemy's Alien Overlord will destroy theirs and keep yours intact if you have one on the field.
