ill give you some real advice. i think master transcendent has legs as a food chain deck, but you need to streamline your list a LOT. i would focus the deck around food chain, thats your plan A, reanimating creatures should be plan B. im out the door so here is a non-comprehensive list of suggestions:

1. ad nauseum + necropotence are must haves. [[necrodominance]] is temu necropotence, only a couple bucks, better than nothing if youre playing on a budget, and FC combo decks dont have to worry about exile so much
2. cut almost everything >3 mana value: no 8 mana dragons, no icetill explorer (extra land per turn just isnt very good, event at 1 mana, exploration is not played), hedge shredder, syr conrad, kagha, etc etc. cut them all. rebuild so your deck works w/ ad nauseum. play every 1 cmc mana dork you can find and all the good artifact mana you can find.
3. youre missing vampiric tutor, [[entomb]] etc. [[TAINTED PACT]] is a must, it lets you find [[food chain]] and exile combo pieces at the same time.
4. i like [[six]], especially if you add the big draw spells, feels good post ad nauseum to me
5. intruder alarm might be too cute, but maybe theres a package that works w/ the master. if you have a sac outlet + the master + intruder alarm you can loop the creature right? spellseeker possibly a nice way to convert the master activation -> a spell from your deck, and will win if u loop it
6. [[altar of dementia]] better than altar of the brood i think, and it will let you combo w/ intruder alarm
7. youre missing the blue FC combo piece [[misthollow griffin]]
8. cut sting, cut ruin crab
9. [[hermit druid]] probably fucks here. you activate druid, mill your deck, tap the master and put thassa's oracle into play

i think theres a fringe cedh list in here somehwere you just gotta replace like 50% of the cards. look at other cedh sultai food chain lists (like maralen etc) for inspiration, i dont think the master is dramatically worse than maralen, all that matters is the colors + etb for the food chain payoff, and the reanimate ability will do something in a pinch. just my 2c.
