You can only use either this card name’s (1) or (2) effect per turn, and only once that turn.
(1) Target 1 “Armed Dragon” monster you control; it gains 1000 ATK for each “Armed Dragon” monster in your GY with a different name with an equal or lower Level to that monster, but all battle damage that monster inflicts to your opponent becomes 0 for the rest of this turn.
(2) You can banish this card from your GY, then target 1 “Armed Dragon” Spell in your GY; add it to your hand.
