@Gattison: Thanks!

@TheEpithet: I've thought about running OG Kalitas, and while the Kaliti would be fun to use together, he costs a lot and wouldn't get me the vampire token because new Kalitas replaces the dying with exile, though I would still get a zombie so not too shabby I guess. To the maybeboard it goes!

Mana Web for the combo with Urborg, Tomb of Yawgmoth so one of your opponents can only tap one land for mana per turn?

This is a nice build. Definitely using a couple ideas for my own Kalitas deck. I think Gatekeeper of Malakir and Withered Wretch are a little weak, but I'm assuming that you're replacing at least one of them with Relentless Dead when it comes out. How well does Thran Dynamo work here? It seems kind of clunky to me. Erebos, God of the Dead seems like a must for this deck, and I would suggest looking at Corpse Augur as well. Ghoulcaller Gisa might be a solid choice too.

Just a thought, but for Lifeline Shenanigans, you could always run Blood Seeker in the event you don't have a Leyline of the Void out. He can put in a surprising amount of work. You can also Cauldron of Souls an opponent's creatures to bounce them while Blood Seeker is out.

@K00lDudE1: I don't think I'll run Mana Web for now, but if I were trying to make a "competitive" build it might make the cut.

@NoSoyYucateco: I'm shying away from Lifeline for now since I feel I would want to build around it more, and I'm pretty happy with the current shape the deck is taking.

@acronix: Thanks! Gatekeeper of Malakir and Withered Wretch are weak in comparison to some other creatures, but are great utility and Kalitas is always happy to eat them for that extra commander damage. Relentless Dead is absolutely going in, but I haven't thought about a cut for it yet. That card is going to be ridiculous. Erebos, God of the Dead is good, so I might slot it in. Corpse Augur is something I'll consider since that could be fun with Mikaeus, the Unhallowed out.

Regarding Thran Dynamo, I'm a huge fan of this card in every mono deck, and this one is no different. It's been great, especially with the number of equipment I'm running. Just the other day I was able to:

• Turn 3: Cast Thran Dynamo and Darksteel Plate
• Turn 4: Cast Kalitas and Lightning Greaves (not equipped yet), equip Darksteel Plate
• Turn 5: Cast Damnation, with enough left over to cast Lashwrithe and start beating down for 7+ per turn

It was glorious.

Forgot to mention, I had Ghoulcaller Gisa in the deck for a while but she was too slow to be effective for my "keep the board clear and voltron up" strategy.

Yeah, I noticed it was no longer mainboarded after I posted that comment. I have one that has been sitting in my trade binder forever, waiting for me to think up some brilliant way of using it that has probably already been thought up a thousand times.
