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.
