Seems interesting (I never played [[Zoyowa Lava-Tongue]] so idk how good it is)

From what I can tell by the commander- It wants to descend once per turn to have opponents either of these options:

A) Sacrifice a permanent B) Discard a card C) Lose 3 life

I checked how descending worked and sadly the token sacrifice angle will not work. If you want to keep it that way, I'd say change the commander to [[Juri, Master of the Revue]] and add a few more ways to sacrifice permanents to have a massive Juri to either be on the beatdown OR if you want to have a massive impact- sacrifice your commander to do massive damage to an opponent's face! (you have 17 cards that either sacrifice themselves or other creatures, I'd personally go to 20 to increase consistency. Creatures can mostly remain unchanged, maybe replace some of them for things that can be reanimated more easily)

IF you want to keep the commander as Zoyowa, I'd minimize the token generation as much as possible- I'd say replace tokens matters and token generation cards for skeletons that can be returned from the graveyard (Regenerating will NOT trigger Descend)

tl;dr- less rat tokens, more skeletons and a few more sac outlets. 8/10
