Dark Synchro Material Monster

Dark Synchro Material Monsters (ダークシンクロ (formatted as exclusively in card text) Dāku Shinkuro Sozai) are monsters used for a Dark Synchro Summon, one of which is a Dark Tuner Monster. You can also use Dark Synchro Substitute Monsters for Dark Synchro Summoning.

Token Monsters, Spell Monsters, and Trap Monsters can be used as Dark Synchro Material Monsters.

If the Dark Synchro Monster requires Dark Synchro Material Monsters of a specific Attribute, you can use a monster with multiple Attributes (like "") as a Dark Synchro Material Monster.

Synchro Material Monsters are sent to the Graveyard, not destroyed or Tributed.

In Yu-Gi-Oh! 5D's and related works, Dark Synchro Material Monsters are merely treated as regular Synchro Material Monsters, and this term does not exist. These Materials became their own category to match the separation of Dark Synchro Monsters and Dark Tuner Monsters from their original counterparts.
