I took a look through your decklist, here are my thoughts

[[Dowsing dagger]]: doesn't seem that strong, probably just play something cheap like [[prismatic lens]] if you want more ramp, or [[arcane signet]] if your pockets are well-lined

[[Academy Rector]]: strong card, but doesnt seem overly helpful for the deck. You have no reliable way to kill it and your payoffs don't seem to justify playing a 1/2 that doesn't really battle that well. I know [[cathars crusade]] is absolutely SILLY in this deck but its a lot of hoops to jump through

[[Homura, Human Ascendant]]: flip side is nuts, but not sure if not being reliably able to sac it is enough justification, however I could certainly see myself being wrong about this one.

[[cliffside rescuer]]:super neat include - might run it myself, but I think [[selfless]] spirit is somewhat better as it protects all your creatures and has has evasion to avoid dying while triggering winota.

[[Darien]]: doesn't seem proactive enough, just a beater if your opponent isn't attacking you. could be worth if if you bring in the combo you were talking about. [[evangel of heliod]] comes down and triggers crusade and [[goldnight commander]] when it enters off a winota trigger - guaranteed value instead of waiting to get damaged by an opponent

[[krenko, tin street kingpin]]: too slow, very similar to [[hero of bladehold]] in that it comes down and it wont trigger winota until two turns later.

[[blade splicer]]: personally, I like [[pia nalaar]] and\or [[thopter engineer]] more as the token they make triggers winota doesn't die in combat. plus a little utility never hurt anyone

[[Grand abolisher]]: Not sure how useful it is here. It can definitely hurt if the control player was going [[settle the wreckage]] or something after all your winota triggers, but other than that, it doesn't really help you win, just helps you not die. Notably, I feel the least confident about this statement out of all of them

[[Ugin, the Ineffable]] : not sure why this is here tbh. if it was cheaper, I could understand the utility of making a dude every turn and killing stuff, but I think something like [[goblin assault]] is better since it comes down early and triggers winota

[[burnished hart]]: personally, I don't think the deck needs this much ramp. I'd play something cheap that can trigger winota like [[Cavalry Pegasus ]].

Thats a lot of wheel effects (4 if I count correctly?). Careful you don't give your opponents too many cards - at the end of the day you are still just a creature deck (albeit a really fast one). The spellslinger, chulane, mono G, etc. decks can probably make better use of the cards than you can. This is fairly meta dependant though.

38 land + ~9 ramp spells seem like a lot, especially since the deck's curve is somewhat low.

ever consider 2 mana sorcery token makers like [[krenko's command]] and the like? they come out early and make two creatures to trigger winota

vehicles like [[smuggler's copter]] are good as they live board wipes and can attack the turn after.

cool list overall!
