Omni + Venser = Infinite. Remove Venser/Aethersnipe.

Omni + Yarok can make multiple infinite combos. Maybe just accept Omni as scary?

Include a waste for terramorphic during field of the dead? -1 Forest + 1 Waste?

Current infinite combos that I can see
Yarok + 2 Cobras + Ashaya + Venser:
Bounce Venser & (not Seed) Cobra, then replay Cobra to net 1-2 mana

Yarok + Ancient Greenwarden + Cobra (not Seed) + Ashaya + Venser:
Bounce Venser & Cobra, then replay Cobra to get 2 landfall for 0 mana

Yarok + Cobra (not Seed) + Ashaya + Kodama + Venser:
Bounce Venser and Cobra, then place both, then bounce Venser to net 2 mana and Capsize

Something about Riftseeker + Aurora.
Mikokoro + Riftseeker + Aurora(draw deck):
Use Aurora to deploy deck. Cast Riftseeker. Draw with Mikokoro.
Infinite mana (for everyone) and draw deck (for everyone).
The preconditions are not this harsh:
I can recur some cards to hand before an Aurora.
I can tutor some cards from deck to hand.
I have draw + landramp cards.
The question is how large of a deck results in an eventual brick?

Yarok + Venser + Kodama + Cobra:
Bounce Venser and a basic land -4 mana
Replay the land with Kodama (1 trigger unused) +3 mana
Add anything (Greenwarden +1) (Cobra +2) (Ashaya +2) and it goes infinite landfall.

Yarok + Venser + Kodama + Cobra:
Bounce Venser and a basic land -4 mana
Replay the land with Kodama (1 trigger unused) +3 mana
(every odd time) Replay Venser with Kodama bouncing Venser and a basic land
(every even time) Replay the land with Kodama +3 mana
Costs 5 mana to start. First half is -1 mana. Second half is +2 mana.

Tooth and Nail (Entwined):
Yarok +2 mana: Kodama, Runescarred Demon (Venser and Cobra), Kodama Venser x2 to bounce Venser and 2 untapped lands, Cobra, Kodama 2 untapped lands, generate 6 mana, Venser bounce 1 land, Kodama 1 land and Venser (bounce the land), lose 1 mana, Venser bounce 1 land, Kodama 2 lands, generate 2 mana. Repeat Venser for infinite mana.
Yarok & Cobra +0 mana: Kodama, Runescarred Demon (Ashaya and Venser), Kodama Ashaya and Venser to bounce Venser and 1 untapped land, generate 4 mana, Venser bounce 1 land, Kodama land and Venser (bounce something), generate 2 mana. Repeat Venser for infinite mana.

The deck's thematic core (cards recycling) is card advantage so I can cut down on other card advantage cards. However I still need to get cards to the graveyard to make reanimation relevant.

Likewise I discovered it is very mana greedy. One way to handle that is with Awakening and Seedborn Muse (and other mana multipliers) as long as I keep flash and don't accidentally ramp out of theme range and into wincon range. Villainous Wealth costs 10+ mana but is not a concern. Exsanguinate costs 22+ mana. So I want to ramp to 10-15 mana rather than to 20+ mana. A single doubler should be fine and I will have higher prioritizes than finding another doubler (probably avoid Nyxbloom).

Reminder, tutors and recusion can help lower the card count for specific effects. Dictate of Karametra + Awakening might be the smallest multiplier package I could run.
