Montage Dragon
Nearest-era rulings (Tengu, Sept 2011) — no REDU-specific archive exists.
Card effect (current official text)Cannot be Normal Summoned/Set. Must be Special Summoned (from your hand) by sending 3 other monsters from your hand to the Graveyard, and cannot be Special Summoned by other ways. This card's ATK becomes the combined original Levels of the sent monsters x 300.
Rulings
- You cannot Special Summon Montage Dragon while Macro Cosmos or Dimensional Fissure, etc. is face-up on the field because you cannot send Monster Cards from your hand to the GY.
- If you send a WATER monster from your hand to the GY while A Legendary Ocean is active, the original Level of the monster is used and not the reduced Level.
- If Montage Dragon is flipped face-down by Book of Moon, etc., when it is flipped face-up its ATK is 0.
- If Skill Drain is active while Montage Dragon is face-up on the field, its ATK becomes 0. If Skill Drain is later negated or removed from the field, its ATK remains 0.
