Yet another summon bug [Investigating]

Gun Bunny

Black/white node of Emrakul's Corruption states the objective is "summon two or more vampires", and summon has recently been explicitly defined by the devs as putting creatures into play, regardless of method.

I cast concoct three times, pulled three vampires from the graveyard, got zero credit for them.

Thank you for the report. I'll relay this information to the team for review.
