Like any FTK deck, the aim is to win without giving the opponent a turn to play
We do this by inflicting damage with Soulbreaker Armor.
By using ultra polymerization to set Benkei's defence to 0, we can burn the opponent for 3500 with reach Soulbreaker activation.
Big Benkei is easily searchable, so we can we just dig through the deck with Saryuja to find an ultra poly.
To get Soulbreaker into the grave, we can discard it from hand using scarecrow or Barricadeborg Blocker. Also, it can be equipped to a monster that is then used as link material. Either by its own effect or by Union Carrier. Finally, Curious can send a copy directly from the deck. Be carful to only send one Soulbreaker Armor to the grave at a time, since it's effect banishes all copies from the grave to activate.
