Signore dei Draghi Kolaghan

Casting a spell face down won’t cause Dragonlord Kolaghan’s last ability to trigger. A spell with no name can’t have the same name as any other card.

If an opponent casts a creature spell with delve and exiles all cards from their graveyard with the same name to help pay its cost, Dragonlord Kolaghan’s ability won’t trigger.
