Card effect (current official text)If you control a face-up "Gladiator Beast" monster, you can Special Summon this card (from your hand). You can Tribute this card to target 1 face-up "Gladiator Beast" monster you control; shuffle that target into the Deck, then Special Summon 1 "Gladiator Beast" from your Deck, and treat it as if it was Special Summoned by the effect of a "Gladiator Beast" monster.
Rulings
(1) If you control a Gladiator Beast monster, you can Special Summon this card. (2) You can Tribute this card to return 1 Gladiator Beast monster you control to the Deck, and then Special Summon 1 Gladiator Beast from your Deck. The Special Summoned monster is treated as if it was Special Summoned by the effect of a Gladiator Beast monster.
- The (1) Unclassified Effect Special Summons this card without starting a Chain.
- This effect does not activate.
- The (2) Ignition Effect activates & resolves on the field.
- Tributing this card is a cost.
- This effect targets 1 face-up Gladiator Beast monster you control. You can even target a Gladiator Beast Fusion Monster, it is returned to the Extra Deck when this effect resolves.
- If the target is flipped face-down / leaves the field / cannot be returned to the Deck, you do not Special Summon a Gladiator Beast monster from your Deck.
- You can Special Summon the same Gladiator Beast monster that you returned to your Deck, unless the Gladiator Beast monster has an effect preventing you from doing so, like Gladiator Beast Alexander.
