Call of the Mummy
Card effect (current official text)Once per turn: You can Special Summon 1 Zombie monster from your hand. You must control no monsters to activate and to resolve this effect.
Rulings
- When you activate the effect of Call of the Mummy, you can Special Summon a high-level monster from your hand like Giant Axe Mummy or Vampire Lord, but not a Special Summon-only monster like Fushioh Richie.
- You can only activate Call of the Mummy’s effect during your Main Phase.
- You select a monster from your hand when you resolve Call of the Mummy’s effect, not when you activate the effect.
- If you have multiple copies of Call of the Mummy in play, you can only Special Summon 1 Zombie because when you try to activate the second Call of the Mummy, you now have a monster on your side of the field so its effect does not apply.
