This involves a combo that i use in my deck, I'll tell how it works:
First, I get out any creature that costs 3 mana. Then I play
Eldritch Evolution and sacrifice the 3 mana creature. I then go into my library and bring out
Goblin Dark-Dwellers. Then since
Eldritch Evolution hasn't been exiled yet, I use
Goblin Dark-Dwellers's ability to cast
Eldritch Evolution again for no mana. I sacrifice
Goblin Dark-Dwellers to get out some 7 cost creature.
Basically the main question is, does
Eldritch Evolution instantly go into
exile, or before the spell is resolved, it goes into the graveyard so i can use Goblin Dark-Dweller's ability? If this works, it is a huge boost to my deck, thanks for looking.
Oh and sorry if it's a bit confusing. I have issues explaining my problems :/
