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.
Because this deck has been out of the meta for a while, we do not have enough statistics on the deck to generate an up-to-date breakdown. See below for the most recent available decklists.
- 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.
