Looking for some fine tuning on Yoshi/Reyhan

My friends and I have a pod of decks that are specifically meant for the bracket 4, degenerateEDH power level. It's a small pod, so I'm usually playing against the same 5-7 decks, mostly Magda, Kess, Elas-Il Kor, Aeve Elfball Food Chain, Satoru, Chatterfang, and Krenko.

Some hallmarks of our pod are a notable lack in blue, not running the very best fast mana, and smaller and less robust interaction packages. We're also not playing the most over the top "good stuff", though it crops up here and there. You won't see a Gaea's cradle or a force of will, but you might see a Nykthos or a pact of negation.

My deck is an abzan pod style deck, built around combos involving legendary creatures or 1/1 counters. I'm not as fast as our fastest decks, but I'm much more resilient than any of them. Lately, I've been toying around with the list a lot, bumping up the power here and there, and cutting cards that felt dead. That included a lot of stax pieces, and now I'm left with this pile. I feel pretty solid about it, but I've been trying to find some pieces that feel a bit more modal, something like [[Shigeki, Jukai Visionary]], a recent addition.

I'm looking for additions to the deck that fill multiple necessary functions like card draw or mana, without being more of the generic cEDH staples you might see. I'm not looking to Tayam a Ranger-Captain of Eos repeatedly, and even Ad Nauseam is on the chopping block for power level. Are there any cards I'm missing from this list that you think might provide some benefit to this deck?

TLDR, what are some nice modal style cards for an Abzan pod deck that aren't just basic cEDH staples?
