The effect of the “Gladiator Beast” monsters that says, “At the end of the Battle Phase, if this card attacked or was attacked, you can return it to the Deck…”, returning the “Gladiator Beast” monster to the Deck is a cost to activate the effect.
The ② effect:
If you do not have any “Gladiator Beast” monsters remaining in your Deck that you can Special Summon, you cannot activate the effect of the “Gladiator Beast” monster that attacked or was attacked. For example, if “Gladiator Beast Murmillo” attacks or is attacked and the only “Gladiator Beast” monster remaining in your Deck is another copy of “Gladiator Beast Murmillo”, you could not activate the effect of “Gladiator Beast Murmillo” at the end of the Battle Phase.
It can't be activated unless there is a "Gladiator Beast" monster in your Deck.
If a “Gladiator Beast” monster attacks or is attacked during the Battle Phase and the “Gladiator Beast” monster becomes flipped face-down by an effect during the Battle Phase, even if the “Gladiator Beast” monster is flipped face-up before the end of the Battle Phase its effect to Special Summon another “Gladiator Beast” monster cannot be activated.
It can activate and resolve while "Skill Drain" is applying (without being negated).
“Divine Wrath” can be chained to the effect that returns the “Gladiator Beast” to the Deck. The effect will be negated, but the “Gladiator Beast” monster will not be destroyed because it is in the Deck.
It can be negated by "Royal Oppression" (If it is, this card remains in the Deck (it is not destroyed)).
If 2 or more “Gladiator Beast” monsters attack or are attacked during the Battle Phase, at the end of the Battle Phase the effect of each “Gladiator Beast” monster can be activated. The effects will activate and resolve separately. They are not combined onto the same Chain.
"Battling" requires this card to be involved in Damage Calculation (If this card's attack is negated, the ② effect can't activate).
If a “Gladiator Beast Alexander” is Special Summoned and later it is removed from play using “Interdimensional Matter Transporter”, when it is returned to the field its “unaffected by the effects of Spell Cards” effect will still be applied.
If multiple "Gladiator Beast" effects are activated at the end of the Battle Phase, they don’t go on the same Chain (they each activate, one after another, each on their own Chain). Vs "Rivalry of Warlords"/"Gozen Match":
If a “Gladiator Beast Alexander” is Special Summoned and later it is flipped face-down by another card’s effect, when it is flipped face-up the “unaffected by the effects of Spell Cards” effect will not be applied.
If you have a Gladiator Beast of the same Type/Attribute in your Deck, you can activate the ② effect. If you do, you can Summon any Gladiator Beast of any Attribute.
You can return face-down 'Gladiator Beast' monsters to your Deck to Special Summon a 'Gladiator Beast' Fusion Monster, but you must show your opponent the 'Gladiator Beast' monsters to verify that they are correct.
If you take control of your opponent's 'Gladiator Beast' monster and attack with it during the Battle Phase, you can return it to your opponent's Deck to Special Summon a 'Gladiator Beast' monster from your Deck if you have a 'Gladiator Beast' monster in your Deck that you can Special Summon..
You can use a 'Gladiator Beast' Fusion Monster when Special Summoning another 'Gladiator Beast' Fusion Monster. The 'Gladiator Beast' Fusion Monster that you use for the Special Summon is returned to your Extra Deck.
You can activate "Torrential Tribute", "Bottomless Trap Hole", etc. when a 'Gladiator Beast' monster is Special Summoned at the end of the Battle Phase.
If a 'Gladiator Beast' monster attacks and its attack is stopped with a card effect ("Gravity Bind", "Spellbinding Circle", "Enemy Controller", etc.) or is negated during the Battle Step, the 'Gladiator Beast' monster cannot activate its effect at the end of the Battle Phase.
