Gladiator Beast Nerokius

Regarding "Must be Special Summoned (from your Extra Deck) by shuffling the above cards you control into the Deck (you do not use 'Polymerization')": * This is not treated as an effect. It is a method/procedure for Special Summoning this card. * In principle, this is the only way to Special Summon this card from the Extra Deck. However, if an effect "ignores the summoning conditions," you can ignore this text and Special Summon this card from the Extra Deck. * If this card was Special Summoned by this method and is subsequently sent to the Graveyard or banished face-up, you can Special Summon this card with other card effects. * This method of Special Summoning does not start a Chain Link. * This Special Summon is not a Fusion Summon. However, the monsters used for this procedure are shuffled into the Deck as Fusion Materials. (You cannot shuffle monsters that "cannot be used as Fusion Material" into the Deck/Extra Deck to Special Summon this card.) * You can choose Fusion Monsters or Link Monsters as the monsters to shuffle into the Deck. In that case, those monsters are returned to the Extra Deck. * The "3 'Gladiator Beast' monsters" to be shuffled into the Deck must all be chosen from your Monster Zone. (You cannot choose them from your Spell & Trap Zone.) * You can choose your face-down cards as the monsters to shuffle into the Deck. In that case, you must reveal them to your opponent to confirm they are appropriate Fusion Material monsters. * The Special Summon occurs after the specified cards are shuffled into the Deck (or Extra Deck). These do not happen simultaneously. * If you shuffle this card into the Extra Deck as a Fusion Material, you cannot Special Summon this card itself. (The monster shuffled into the Extra Deck as a Fusion Material and the monster Special Summoned from the Extra Deck must be different cards.)
