TCG Rulings

  • The effect of “Debris Dragon” is a Trigger Effect that activates when it is Summoned and targets 1 monster in the Graveyard. “Debris Dragon” does not continue to target that monster after the other monster is Special Summoned.[1]
  • If “Debris Dragon” Special Summons a Gemini Monster, the Gemini Monster’s effect that makes it a Normal Monster is negated, so the Gemini Monster is considered an Effect Monster.[1]
  • You cannot use “DNA Surgery”, naming Dragons, to use “Debris Dragon” to Synchro Summon a non-Dragon Synchro Monster. The Synchro Monster must originally be a Dragon-Type monster.[1]

OCG Rulings
