I'm looking for wrinkles in my blue/black Zombies, and I bring this one before the Hive Mind so I can iron it out.
Hypothetically: Grimgrin, corpse-born
is on the field tapped. I have, say, diregraf ghoul < span> on the field untapped.
Opponent's turn, he/she attacks with two creatures.
Can i declare my ghoul as a blocker, sacrifice it to Grimgrin, untap him, and declare him as a blocker as well?
I have this feeling i have to declare my blockers all at once. Grimgrin will be tapped at the time and so i can't block with a chump and Grimgrin in the same block step.
But I must know for certain.
