I am playing an Edgar Markov deck with plenty of 1/1 tokens and an Indulgent Aristocrat on the field.
Indulgent Aristocrat has the ability
{2}, sacrifice a creature: put a +1/+1 counter on each vampire you control.
My opponent is playing the Enhanced Evolution precon, and casts Chittering Harvester for its mutate cost. Chittering Harvester has
whenever this creature mutates, each opponent sacrifices a creature
My question is this: Can I choose to sacrifice a 1/1 token to Chittering Harvester, and then, before resolution, activate Indulgent Aristocrat's ability hitting the same token?
