I had been using Altar of Dementia in a previous build but found the only creature worth sacking to it is Consuming Aberration where the Altar of the Brood constantly mills throughout the game and allows more flexibility the turn I play it due to the lower cost. Propaganda sounds good, I will give it a try.

Thanks for looking at it!

Maybe swap of Altar of Dementia in for the Altar of the Brood. It you can tap an Aberration, cast Harvest, then sac it for an insane amount of mill potential. Maaaybe give Propaganda a chance over Narcolepsy? It's to their whole field and can ruin aggro decks.

Thanks for the suggestions and the upvote! :D

I agree that Gravecrawler Is much better suited than Diregraf Ghoul, but the Ghoul has a much friendlier price tag than the crawler. Aside from the fact I only have 1 Gravecrawler right now, the price is the reason i haven't used it too much....maybe someday, but not today.

I did not realize Altar of Dementia wasn't modern legal....Undercity Informer is a great card, but I'm really trying to stay tribal with Zombies, so that's not exactly going to work with my other cards. Empty the Pits is something i could definitely see using, same with Mesmeric Orb except for the whopping $10 price tag. lol

@foxboy93, I'm aware of this, but in tournaments the judges will ask you to play it out always, and the odds of such an event occurring from a 100-card deck is very slim that you won't see it played as the win-con. Yes, I know play groups are different then tournaments, but a lot of play groups will ask you to play it out like a judge would especially if they put the eldrazi titan in their deck specifically for that purpose of defeating mill, which most people I've met will say that's the reason why when its a clunky 10 or 11cmc spell that has zero-interactions with their own deck

In defense of Altar of Dementia it's great to use its mill-effect on yourself if you desperately need a combo-piece in your graveyard, but I don't see any other great uses. You could try to line it up with graveyard-hate, but that adds another piece to the combo and most graveyard-hate will ruin most sac-loops you'd create with your Altar of Dementia, but that's just my opinion on the matter.

I'm surprised you run Altar of Dementia as a combo piece. I had to pull mine out, because my opponents would always have either; Emrakul, the Aeons Torn, Kozilek, Butcher of Truth, or Ulamog, the Infinite Gyre in their decks making them impossible to be milled since the titans would just reshuffle their graveyards back into their decks.

I would advise running Goblin Bombardment since it will do infinite damage guaranteeing you a win. If the red mana is too harsh for a deck that runs Contamination then I'd suggest using Blasting Station which works just as well. Nice work on the Alesha deck by the way.

Last night in a four-person game, got the combo off. I had Undead Alchemist, Altar of Dementia and Geth, Lord of the Vault on the field. Tutored for and dropped Altar of the Brood, then used Geth to put a 6-drop from opponent's graveyard on to the field. Opponent milled 6 and I got two Zombies. With the Brood, each opponent milled three, got another Zombie and another mill. At one point, it stalled so I sacked several Zombies to Altar of Dementia and restarted the whole process. Ended up winning the game without attacking. Had 47 Zombie tokens on the field and all opponents were milled.
