Vortex Synchro Monsters

Vortex Synchro Monsters are a special set of Synchro Monsters, similar to Accel Synchro Monsters, but with a twist. Vortex Synchro Monsters can also count as Fusion Monsters, and, once per turn, during any player's turn, can act as either a Synchro Monster or a Fusion Monster until the end of the turn. This allows anti-Synchro cards to be rendered ineffective and prevents cards such as Discord. Vortex Synchro Monsters always have the same beginning text: ''This monster also counts as a Fusion Monster. You may Fusion Summon this monster with the above Material Monsters. This monster cannot be Special Summoned except by Synchro Summon and Fusion Summon. Once per turn, during either player's turn, you may treat this monster as a Synchro Monster or a Fusion Monster only, until the end of the turn.''
