I don't think I can really comment a ton on this deck without some more context as to what the combos are that you're going for. There do appear to be some infinites in the deck but I can't pick them out by eye.
From the looks of things you're probably looking to set up a nearly infinite
Villainous Wealth, but I can't see anything that cleanly combos with
Kydele, Chosen of Kruphix so I might be missing something.
The
Demonic Consultation /
Thassa's Oracle /
Laboratory Maniac packages really feel at odds with what the deck is doing to me, and I wouldn't play them at this power level. I'd like to see the lab man/consultation stuff be more supporting things.
With that said, my main thoughts are
* The ramp package is a bit disjointed with creature ramp and stuff like
Cultivate. My gut perspective is this is a deck that wants more
Kodama's Reach effects but you also need to enable Tevesh with creatures to sac and block. I think I would probably add
Far Wanderings honestly, given that you are going to sac things and have a bunch of saccy dudes.
* Without much of a reanimation package I don't love a lot of the big dudes like
Dragonlord Silumgar and
Sphinx of Uthuun. These seem to be just goodstuff and not really part of the plan. I'd like to see all your big stuff synergize with
Kydele, Chosen of Kruphix or
Tevesh Szat, Doom of Fools somehow.
Imagine
Sire of Stagnation potentially allowing you to go infinite off another player's
Skyshroud Claim when you draw 4.
* Combo package wise, I really prefer
Staff of Domination as my combo outlet with Kydele over the consult package. It's not as neat and tidy but it's way more interesting.
*
Black Market is a sweet card but I think this deck wants a couple sweepers to support that plan. Maybe
Toxic Deluge at least? Or
Apex Altisaur and a reanimation package?
* I kinda like the idea of a small theft package to steal other people's commanders and sac them to
Tevesh Szat, Doom of Fools but I might be overthinking
Maybe something like
Treachery or even
Reins of Power if you go up on sac outlets. I'd definitely play
Gilded Drake but that's kinda gotten out of the affordable realm these days.
Anywho, I think there's a lot of cool stuff at play here with Tevesh / Kydele being able to make her tap for 3 just by saccing a dude. So cool combo, just need to focus a bit!
