Making Doomsday work

I’m curious to hear how you make [[Doomsday]] work in your favor.

I’m not totally unfamiliar with the card as I have it as a wincon in my [[Grenzo, Dungeon Warden]] deck, where the idea is obvious: play Doomsday, get the combo cards and use Grenzo to end the game the same turn.

But what are your ways to utilize Doomsday?

Reason I’m asking: I’m having a lot of fun with my upgraded Doom Prevails pre-con and would love to add as many Doom cards as possible, including the new Doomsday reprint, for obvious flavor reasons. I do run [[Doctor Doom, Unrivaled]] in the 99 which sort of plays well with Doomsday, but that’s about it.

Are there any fun ways to profit from Doomsday in Grixis discard, or is it just a dead card taking up unnecessary space?

Tanks in advance!
