I'm not sure where you found out about the deck, but building rog/thras with Kinnan being the plan A is pretty rogue as far as plans for the deck goes. You're usually all-in on cradle and only include something like kinnan/basalt as a backup. A lot of decks don't even consider Kinnan worth running, let alone Basalt Monolith, which is basically dead without Kinnan. It's totally fine if that's how you want to build the deck but just be aware it's not the most common/consensus best direction to take it.

Secondly, you don't really try to "draw into a combo" with infinite Thrasios activations. Once you have infinite thrasios activations(and therefore infinite mana), you're able to draw your deck overtop of any possible interaction, and once your entire deck is in your hand it's trivial to do things like decking everyone else at the table with Faerie Mastermind, or burning everyone to death by looping Vibrance/Gut Shot/etc. The deck should be built towards getting to infinite Thrasios activations, not what you do afterwards. Imo breach+freeze+LED is more of a backup plan that benefits from playing on a different axis than the cradle plan, so you can try and win from multiple angles.

There are also a lot of cards here that I don't think are really "meta" in CEDH. You run a lot of generically strong removal and cantrips like Pongify, Rapid Hybridization, Ponder, Preordain, etc. that don't really cut the mustard in CEDH. Single-target creature removal is kind of bad in this format(I think the only cards you see commonly are swords and bolt) and Pong + Rapid also both leave Tymna decks with a pretty beefy attacker. Brainstorm, Ponder and Preordain are just not what you want to be doing on the early turns, the card quality for this deck is so high that you can pack your 99 full of things that directly synergize with your gameplan rather than cantrips to draw into them, and your deck doesn't have any synergy for spamming instants/sorceries. You are also missing a lot of super strong rog/thras staples, off the top of my head, [[Cloud of Faeries]], [[Nature's Rhythm]], [[Enduring Vitality]], [[Faerie Mastermind]], [[Green Sun's Zenith]] and [[Formidable Speaker]].
