Hmm.. about your Ramp: what about Orzhov Signet and Fellwar Stone? Both are very budget friendly.
Then, as already mentioned at your Muldrotha deck, Diabolic Intent could be an interesting (but not that cheap) option.
Do you really need Scoured Barrens? I think it could be replaced with a basic land or Exotic Orchard for a little more speed. Same goes for Terramorphic Expanse.
For carddraw, Well of Lost Dreams?
If you need some more control, Gideon's Intervention and Darksteel Mutation could be interesting, especially to shut enemy commanders down.
For recursion: Oversold Cemetry and Sun Titan could be interesting.
All of my current ramp synergizes with Teysa (except for
Commander's Sphere &
Sol Ring), so I don't really want to trade out some synergy.
I would like to run
Diabolic Intent, what should I cut? I'm thinking
Strionic Resonator because only a few of my triggers are worth the mana and hassle. Do you know if the additional trigger from
Strionic Resonator triggers an additional time because of
Teysa Karlov's ability? It doesn't, right?
I'm not that worried about taplands. My group is non-competitive, and during the early-game, my deck is designed to look weak, so I won't attract attention. I am more worried about hitting the right colors than losing a bit of tempo.
My deck isn't themed around life gain at all. It is an Aristocrats-Tokens deck. If I wanted to run life gain, then I'd add
Dawn of Hope.
I would like
Darksteel Mutation, but my removal slots are pretty tight. What do you think would be a good cut?
Sun Titan doesn't synergize with Teysa, and he doesn't go infinite with
Reveillark like
Karmic Guide does. Plus he has a high mana cost.
Oversold Cemetery is nice, but it's missing a couple things:
1. It has the requirement of 4 or more creatures in the yard, which I don't want to rely on.
2. It says to put the returned card to my hand, which I don't like as much as to the battlefield.
I just like
Phyrexian Reclamation more as a cheap, repeatable piece of reanimation.
