I played this last night against
Mogis, God of Slaughter,
Omnath, Locus of All, and
Elesh Norn, Mother of Machines. Just to get ahead of things, there was a UI "thing" that greatly affected the game so it might not be a true indicator of the deck.
I started off by needing to mull to 6. My first hand had
Mana Crypt but only one land (
Winding Canyons) and the second hand had 0 lands. I was able to keep a hand with enough lands but not much in the way of ramp. It still let me get Ephara down turn 4. The main issue was the lack of creatures to trigger Ephara. So things were a bit slow going to really do a lot. I mainly had
Remorseful Cleric out as my only creature for 2 or 3 turns.
In the mean time, Mogis was getting their commander down along with things like Blood Sun. They did try to cast
Painful Quandary but I had to counter that. Elesh Norn got their commander down too and was able to start getting a few things going. Nothing big but
Priest of Ancient Lore coupled with
Teleportation Circle allowed them to really keep their hand full. And there wasn't much I had to deal with it.
Beyond this though, the game was not moving much at all. Omnath was doing very little and Mogis was doing a couple things (like
Skull Rend) but beyond that not much was happening.
I was able to get a couple other creatures. I cast
Stormscape Familiar which let me draw a card but the other cards in my hand had ETB triggers (
Spell Queller and
Glorious Protector) which Elesh Norn shut off. However, the weirdest thing happened around this time: Mogis cast
Illicit Auction targeting Elesh Norn. That, in itself, isn't that odd but the UI messed up at least one person. Instead of the UI asking you what you want your bid to be, it asks how much you want to raise it. So, Mogis started it somewhere, Elesh Norn went to 7, Mogis went to 27 (I am not sure if they wanted to be at 20 or raise 20), and then Elesh Norn clearly wanted to bid 32. However, they instead *raised* it 32 which put it at 59. Which they didn't have so they immediately lost the game.....
From there, Omnath started trying to build a board and got out
Grave Titan followed by
Hoarding Broodlord while Mogis tried casting
Erebos, God of the Dead. I countered Erebos with Spell Queller. Omnath then cast
Underworld Dreams and
Midnight Banshee. The Banshee would eventually wipe my board but there wasn't much I could do about it.
Mogis then cast
Exsanguinate which I let go. It put me to 14 and Omnath to 9. It got them back up above 20 I believe. However, right after that, Omnath cast
Peer into the Abyss targeting Mogis which killed them. This ended up working out great as it got rid of someone and I had an answer to it if I needed it anyway (
Fierce Guardianship).
Now that it was just the two of us, I tried to go a little more aggressive. I still had the Banshee to contend with but I was trying a few things to get around it since I never drew any removal. I did use
Venser, Shaper Savant to bounce it for a turn but it just came back. They then cast
Bolas's Citadel which I let go since they were at a low life total anyway. They then tried to cast Omnath which I did a bit to counter and win the game at the same time. I cast
Glorious Protector to exile my Venser and
Spell Queller. I then cast
Prized Amalgam to sacrifice Glorious Protector to get back Venser (Spell Queller couldn't do much but this did remove the counters on it) and used that to bounce Banshee. Amalgam countered Omnath. So, now, I was tapped out and they had no creatures on board whereas I had 4 now that Ephara was turned on.
Omnath then tried to cast
Damnation with their remaining mana but I cast Fierce Guardianship for free to counter it and they scooped.
Beyond starting off slow with few creatures, the game ended up going pretty well. I doubt it would have though if Elesh Norn was still around as that does shut down this deck pretty well. And I am not sure I ever really got to an answer for it (though I might have since the game likely would have gone on longer). In any case, I was pleased with how things worked and don't have a strong opinion of things that need to change at this time.
