Target 1 "Armed Dragon" monster you control; it gains 1000 ATK for each "Armed Dragon" monster in your GY with a different name and an equal or lower Level than that monster, but it cannot inflict battle damage to your opponent this turn.
You can banish this card from your GY, then target 1 "Armed Dragon" Spell in your GY; add it to your hand.
You can only use 1 "Armed Dragon Thunderbolt" effect per turn, and only once that turn.
