I like that you've kept all the comments over the years. To think there was once a time when we could think "let's not run Cabal Coffers in this mono black EDH deck!" Amazing. +1.

i love the fact you made a monoblack combo edh deck you can add Sanguine Bond and Exquisite Blood for infinite life gain and life loss on the opponent, also Dark Depths would be a nice combo with Vampire Hexmage

So one combo in here is Vampire Hexmage , Grave Pact (or Butcher of Malakir or Dictate of Erebos ) and Mikaeus, the Unhallowed out (unlimited forced sac). And +1 for the Retribution of the Ancients for removing +1/+1 counters. Life's Finale as well? Maybe Cairn Wanderer ? And also possibly Buried Alive

and where's gary? Gray Merchant of Asphodel

ignore - hexmage dies and doesn't come back ...

I've been working on a Mikaeus, the Unhallowed EDH deck for months. I'm ambitious and the entire deck is infinite combos. Using everyone's comments plus hunter9000 and your awesome expertise, I think my deck is pretty solid. Extremely risky with no early game except for ramp, but the idea is that if Mikaeus resolves, it's basically game over. Awesome, awesome job and thanks for the inspiration! I would love your feedback

Are you really sure about Visara the Dreadful? I get that repeatable removal is good, but a lot of the time your commander is a better card to play, and even if Mikaeus has to be recasted for more she seems like she'll eat removal or wrath.

@jandrobard I use it because it has a big body, evasion, and really great utility. What would you replace it with?

Well, I'm not sure. Pestilence Demon isn't bad, but it's a bit more mana.

I have been running a similar deck for a few months and can only really notice one card that I feel may be lacking. My meta runs a lot of gods, indestructible creatures, and things that make creatures indestructible. This all happened after the meta reached a critical mass of board wipes. I have found Duplicant to be invaluable. It gets rid of almost everything, including those incredibly difficult Eldrazi.

Have you considered Mephidross Vampire? He also goes infinite with Triskelion.

First of all, I love your deck. I've taken it and adapted it. My meta is pretty fast, and this pulled a lot of hate (after I won 3 or 4 in a row,) so I had to speed mine up. I added as many rocks as I could, and had to take out some of the slower combo pieces (Grim Poppet is great, but at a 7 drop it just isn't really viable for me.)

Wanted to ask you though...have you considered Lake of the Dead? It can seriously speed you up a lot.

Turn 1, Swamp, Sol Ring. Turn 2, Swamp, Mana VaultTurn 3, Lake of the Dead. 11 Mana for turn 3, can win you the game turn 3 with the combo pieces.

Also, I highly recommend Arcane Lighthouse in every edh deck. Just too good to not use.

I didn't see it anywhere, but I looked through about half the comments then tl;dr, but Crovax the Cursed seems like an amazing sac outlet for this, especially with Grave Pact.

Also, Cauldron of Souls. 'Nuff said?

Culling the Weak looks really strong here.

OK, awesome deck, +1. There are quite a few cards that spring to mind right away for this deck, like Sadistic Hypnotist, destroys everyone else's hands, and attracts so much hate, but there's very little they can do about it! Dross Harvester gets you infinite life once you get one of your combos going.Blood Artist and Falkenrath Noble get infinite life and infinite damage. Thoughtpicker Witch requires mana, but with a limited amount, you can control your opponent's top deck and with an infinite amount you can mill out everyone. Shadows of the Past gets you the same effect as Viscera Seer, but you need a sac outlet to get it to work. Phyrexian Plaguelord is a sac outlet that wipes the board once you get a fodder out. Also, wouldn't the infinite draw combos with Carnage Altar and Infernal Tribute only work if you have a an infinite mana combo out? I might just be missing something here.

I got all of these card suggestion from my deck I'm SAHRy you have to play against this deck, which is quite similar to your deck despite have different commanders, so there might be a few more cards that you could use.

Can I suggest Walking Ballista from aether revolt as it is just another, cheaper triskellion.

Smileycorp I added walking ballista to my miky build but it actually falls victim to the Micky +1+1 buff just like workhorse. The difference being he can ping himself for infi fodder to grave pactish stuff.

Also micky + walking ballista + blood artist/faulkenrath/alter of the brood works.

Long time viewer of tapped out first time poster. So I don’t know how to link yet. I literally just made an account to tell you the following:

Hex parasite, Blasting station And finally...

TATTERKITE!!!!

Lol I have run a Mikaeus deck for about a year. And all of those cards have done my deck very well

Also, as for a suggestion, I don’t see sidisi, Undead Vizier anywhere. Amazing card. Best Tutor for this deck in my opinion
