How will The sibsig ceremony interact with mutate cards

Asked by ArmchairRuler 3 weeks ago

I was looking at The Sibsig Ceremony and I wanted to know how it would interact with mutate cards like Insatiable Hemophage since the card is technically cast, but as far as i am aware it does not enter the battlefield, but modifies an existing creature. Would I be able to cast the Insatiable Hemophage for its modified mutate cost of 1 Black pip and target say an existing 2/2 zombie druid token on the field to get a 2/2 deathtouch zombie druid token with the additional mutate ability? Or would I just get another 2/2 zombie?

I think that your mutate spells will get the benefit of the cost reduction from The Sibsig Ceremony, since they are creature spells on the stack, but they won't be destroyed, since it mutates onto an existing creature:

"A mutating creature spell is a creature spell, even if it won't enter the battlefield as a creature."

"A mutating creature spell that resolves doesn't enter the battlefield. It simply merges with the target creature. As this happens, the controller of the mutating creature spell chooses whether to put it on top of the target creature or on the bottom. Abilities that trigger whenever a creature enters the battlefield don't trigger."
