If this card is sent to the GY as material for a Fusion Summon: You can Special Summon 1 Fusion Monster from your Extra Deck in Defense Position (but negate its effects, also return it to the Extra Deck during the End Phase), also for the rest of this turn, you cannot Special Summon from the Extra Deck, except Fusion Monsters
So I went back to Part 1, to get Lioside's decklist (AGAIN!)
the player must Duels against 3 opponents in a row, with your Life Points carried over to the next opponent)
Since this card negates the monsters effect, it allows you to destroy the monster without worrying about whatever insane effect that monster probably has
If going against a Deck like Mitsurugi , they cannot summon from their Deck with Ame no Habakiri no Mitsurugi or Mitsurugi Ritual , and they cant search at all, while other decks can play around it to do their plays
We recommend this deck for any new player looking for a place to start
