Playstyle

Souldragon Requiems feature the "Soulbind" ability, which allows their monsters to invade the souls of opponent's monsters on your opponent's fields, filling the soul of the monster with soul cards, but causing the monster to attack the opponent at the start of the opponent's attack phase.
Souldragons gain effects for when the monster they are in the soul in attacks your opponent, so stacking as many of your opponent's monsters as possible is essential.
