Looks great, but I can't find the combos. I guess there should be multiple, and I'm pretty sure Yawgmoth, Mikaeus and Nimm Deathmantle play their part in it, also I guess Sifter of Skulls and Pitiless Plunderer. But I seem to be missing the final piece(s). Could you explain the Rest?

Also, playing Lurrus myself, two great cards to add are Gravebreaker Lamia and Buried Alive. In case you're interested in my list: Sadistic Kitty (Lurrus Eggs)

seshiro_of_the_orochi Thanks for the suggestions. Regarding those cards, I was previously running them in a test version I had. I ultimately ended up pulling them as they ended up being lack luster because I have other cards in the deck that did what they did but better, and also those slots ended up being replaced with better more reliable threats. They are great cards though. I really like them. They just ended up being replaced. So to better understand the combos in the deck. I went ahead and updated the description. I've been meaning to do so for awhile but just never got around to it. I hope this clears up any confusion. Thank you for the love.

You're welcome. I totally understand your reasoning. I'm looking at the Altar + Messenger + Deathmantle Combo and can't help thinking that there's Timing issues:

You sac Messenger for Altar. Messenger and Deathmantle both trigger. You don't pay for Deathmantle this time, but Undying brings back Messenger. Altar resolves. You sac Messenger once again, and this time, you'll have to pay for Deathmantle, but you'll have to do so before Altar resolves, so you have to pay the floating from the first Altar Resolution, and from other sources. And while writing that down I realized that this issue only appears in the first cycle of the combo. It definitely is something to be aware of if you don't have any way to pay These additional .

Requires: All permanents on the battlefield. Steps: Sacrifice Geralfs Messenger to Ashnods Altar, producing Geralfs Messengers returns due to undying and deals 2 damage to target opponent. Sacrifice Geralfs Messenger again to Ashnods Altar, producing Activate the ability of Nim Deathmantle using the mana from Ashnod's Altar and return Geralfs Messenger to the field. Repeat.

It can also be done if I have a Pitiless Plunderer, Sifter of Skulls or a Pawn of Ulamog and a Phyrexian Altar or an alternate free sac outlet such as Carrion Feeder on the board with at least 2 of the 3 mana producing creatures on the board. As long as your always be able to produce at least each time it dies. You will be able to afford Nim Deathmantle's triggered ability. How the deck does it can be done with multiple different cards. The combo I listed is just the simplest way of doing so. Remember you get to choose the order of the procs on the stack when the creature dies.

Answer to your first post: That's exactly where there's the Tina issue I mentioned: You don't have the from the second activation of Altar by the time you have to pay for Deathmantle. This will only occur during the first "round" of the combo, but you'll have to be aware of it.

*tiny instead of Tina.

seshiro_of_the_orochi I think your over thinking it. Once you sac the creature to Altar is instantly produces . No need to worry about the timing/stack. It happens instantaneously since its a sac and not a spell being cast.

I mean its a mana Ability. Mana abilities do not go on stacks and happen instantaneously. Faster then fast. Quicker then Quick.

I always tend to forget that. Thank you for clarification.
