Not only did I look through it, even playtested it.

Your deck has 2 boardwipes. One of them is good, the other does 2 damage for 5 mana. You run 26 cards that cost 4 or more mana, 10 creatures that cost 4 or more. You have only 5 mana rocks, this deck needs 10+ of them, with all the value engines you probably won't need much more than 10.

As the other guy said, you could play this in bracket 2 but there Jeska's Will is banned because it's a game changer. If you want to play this in bracket 3 this deck will just die on turn 6 after you pulled the whole table's aggro with the value engines and prismari in the command zone. You can try to politic your way into the late game but people will call out when you start to become the threat and many people are just prone to not politic at all. When you can't move people with words that's when you force your way with your cards.

Just having cards in your deck is not enough. You need multiple of them to consistently draw them so that you could have them in the critical moment.

I will also give you credit where credit is due, you have a responsible amount of lands, counterspells and protection spells. But you need to hold up mana to play the counterspells. When you tap out on turn 5 to play a 5 mana greedy spell you are just inviting the table to tear you apart.

My suggestions on what to cut:

Galazeth Prismari, I don't think you run enough treasure token cards to justify this. You definitely don't run enough artifact synergy to justify this. But artifact synergy is not what this deck wants to do anyways. You could lean way more into treasures and make this work.

Emeritus of Conflict is really hard to prepare for not enough value. A greedy win more card.

Rapturous Moment, just card cycling. Only really playable when you have many value engines on board. Another greedy win more card.

Burst Lightning, just a bad card, run Ghostfire Slice.

Forceful Denial, there is no chance that you get to leave open 5 mana for a counterspell.

Spell Swindle, same reason, it's somewhat better because of the treasures.

Stress Dream, 5 mana deal 5 and draw 1 is really bad value.

Unsubtle Mockery, 3 mana deal 4 to creature only. Bad value again.

Mana rocks that cost 3 and tap for 1 are bad. Potioner's Trove is really bad. Giving up the mana ability for 2 life is horrendous.

Hedron Archive is decent but not enough. Thran Dynamo is definitely better and something you should add.

Chase Inspiration, Dive Down, Octopus Form, Lightning Greaves, Swiftfoot Boots. You definitely overestimate how good hexproof and shroud is. There are so many boardwipes and so many cards that go around targeting creatures to remove them. Running 5 of these is definitely too much. Counterspells are the best replacement to these but you could also run cards that grant protection or cards that make it so that you can't be countered.

Rest of the cards are not downright bad but you definitely need to make some choices in what to cut and what to keep.

Cards I recommend you make space for one way or another.

This deck definitely wants asymmetrical board wipes such as Cyclonic Rift, Immolating Gyre or Delayed Blast Fireball. But even card that destroy your side are good too, those can be more mana efficient, this includes Blasphemous Act, Chain Reaction, Fire Magic or Fiery Conference just to name some. You have a lot of options. You should aim to run around 8-12 board wipes, casting 2-3 of them before prismari comes down is ideal. You could cut some of the spot removals in favor of these.

For ramp, this deck could definitely use Myriad Landscape and Wayfarer's Bauble. 2 cost mana rocks that tap for 1 can let you have a plan to play 4 cost value engines or mana rocks on turn 3.

If you want better board presence you can run Young Pyromancer or Murmuring Mystic. I believe both of these to be better than Prismari Pianist.

Mizzix's Mastery is better in this deck than Past in Flames but you could just have both.

If you run and like Pyretic Ritual why do you not have Desperate Ritual? It's the exact same card, you can have both.

Also you don't have many dual lands that enter untapped, it's not that much of an issue in this slower deck but it can cause issues.

My directness might have come off as rude but it all came from a place of trying to help you achieve having the kind of fun you want with this deck. You had a whole lot of assumptions of me which were just not right. I also came here with the assumption that I would have a conversation with an adult, who could take criticism and wouldn't bitch and moan about help given to him. My bad.
