REDU format ruling
Summoner of Illusions
Nearest-era rulings (Tengu, Sept 2011) — no REDU-specific archive exists.
Card effect (current official text)FLIP: Tribute 1 other monster, and if you do, Special Summon 1 Fusion Monster from your Extra Deck, but destroy it during the End Phase of this turn.
Rulings
- Tributing 1 monster is a cost.
- You must use Summoner of Illusions’ effect when it is flipped face-up, either by Flip Summon or by being attacked. If you have no cards in your Extra Deck, the effect cannot activate and you do not Tribute 1 monster.
- If you use Dimensionhole on the Fusion Monster summoned by this card’s effect, it will return during your next Standby Phase and not be destroyed.
- If the Fusion Monster summoned by this card’s effect is flipped face-down it will not be destroyed during your End Phase, since the condition is reset when the monster becomes face-down.
