Seems pretty swingy, TBH. It's great if you mill a couple of Bloodghasts on turn 2, or if you can get two crabs on turn 2, but it's very vulnerable to removal- plus it makes the deck even more vulnerable to Chalice.

Yes, sorry I had meant convoke not delve. You need black or green creatures to convoke for Hogaak so any tokens (or creatures) that aren’t those colors have significantly reduced value.
But, I agree that it’s a good thing that there’s not a clear replacement for Bridge.
I mean, if you endstep a haunted dead it still can convoke for one black on your next main phase. Narcomoeba is still a free creature which can be tapped for the colorless part of Hogaak's cost. But the Mill plan is probably not going to be consistent anymore- unless some mad lad goes for the Altar + Abnormal Endurance combo.
If 3 mana isn't too much for an initial investment, then Diregraf Colossus can pump out a fair number of Zombie tokens with Gravecrawler, now that I think of it- but they come into play tapped.
