yooooo so while I wait for all the pieces of my Ayli deck to get here I'm changing my Sydri combo/hate deck into a Breya deck that's faster, more active, and more aggressive. Can I get some advice on what to take out and what to put in?

I'm just not sure at all of what to do with this hot mess.
My suggestions are all going to bear in mind the metagame that I play in, which might not be as relevant to you, but here goes:
-Cut the combo enablers, or at least most of them. Pili-Pala, probably Grand Architect even though it has non-combo applications, Voltaic Construct, Mycosynth Lattice, Thopter Foundry, Sword of the Meek.
-Cut most of the prison cards. Propagands, Ethersworn Canonist, Crawlspace, Darksteel Forge.
-Cut Dromar's Charm because it's not very good.
-Add token generators. Myr Battlesphere, Sharding Sphinx, Pia 'n Kiran, possibly Pentavus. Tempered Steel and other anthems, maybe with Ajani Goldmane.
-Add token payoffs. Jor Kadeen, Marionette Master, Crescendo Of War if you're feeling crazy. Maybe Sword Of The Paruns.
-Add Momentary Blink because it's the best. Probably Eerie Interlude as well.
-This may not work, but consider a minor lifegain subtheme since Breya can gain you life. Archangel Of Thune and Well Of Lost Dreams could do a lot of work in theory, especially if you add a couple more ways to incidentally gain life like Sphinx Of The Steel Wind and Sword Of War And Peace and so on.
-Stealing opposing effects is always worth a slot, even if it's off-theme. Memory Plunder, Phyrexian Metamorph, Blatant Thievery, Spelljack, Debtor's Knell, Grave Betrayal, possibly Wrexial. No need to go nuts with these effects, but they're often nice to have a few of.
-Lately I've been enjoying the hell out of counters with significant upside. Confirm Suspicions and Insidious Will are very good, especially Confirm Suspicions in this deck since clues are incidentally artifacts.
-Add a few goodstuff cards in your colors like Unburial Rites, Reiterate, Recurring Insight, Decree Of Pain, and Rush Of Knowledge.
-Every deck should always be playing Relic Of Progenitus.
I know those aren't real focused suggestions, but that's what comes to mind. Hopefully at least a little of that helps.
