If a Reptile monster battles an opponent's monster, place 1 A-Counter on that opponent's monster at the end of the Damage Step if it was not destroyed. (Once per turn): If an A-Counter(s) is removed, you can add 1 Reptile monster from your Deck to your hand with a level less than or equal to the number of A-Counters removed.
Legendary Quest
If a monster with an A-Counter(s) your opponent controls leaves the field, you can Special Summon "Alien Shocktrooper" from your hand and place 1 A-Counter on each face-up monster on the field.
Legendary Relic
If “Alien Shocktrooper” is Summoned, you can place 4 A-Counters on monsters on the field, distributed as you wish. (Once per turn): You can remove any number of A-Counters on the field; this turn, if you would tribute a Reptile monster you can tribute a monster your opponent controls whose Level/Rank is less than or equal to the number of removed A-Counters instead.
Tip Skills
When you place an “A” Counter(s) by a card effect, place another. This Skill's name is always treated as "Allen and Adrien’s Alienation Immigration Legalization Nation Hydration Lactation Station Socialization Vacation resulting in Hospitalization"
Reptile monsters in your possession are all also treated as “Alien” monsters.
