Dark. Dragon/Effect. 1. If a monster you control is destroyed by battle or an opponents card effect: You can Special Summon this card from the GY (if it was there when that monster was destroyed) or hand (even if not), but banish it when it leaves the field. If this card is Special Summoned: You can target 1 face-up monster on the field; discard 1 card, and if you do, add 1 monster with the same Type and Attribute, but with different name of the targeted monster from your Deck to your hand. You can only use each effect of Omni Dragon Brotaur once per turn.
