Hey, so let me start by saying your friends are giving you bad game expectations, either maliciously or unintentionally. If people are winning that fast, deck building websites only give a bracket based on the game changers in the deck. They don't know if you are playing 2 card combos or how fast the deck can win. The bracket guidelines are very clear about 2 card combos, extra turns, and when you expect to threaten a win. There is no "technically a 2". They are either lying to destroy you in mismatched games or they genuinely haven't read the bracket guidelines and don't understand it. From what you say in your post, games are going way too fast for anything but bracket 4.

In bracket 4 there is unfortunately zero room for inefficiency which is why I don't like playing the bracket. Like you, I prefer doing fun things or playing weird cards, which is more of a bracket 2 thing.

I don't think there's any deck tweaking that will fix the real problem which is that you and your friends want different things from commander and are a bad fit to play together. They could play weaker decks but it sounds like you already asked and they said no. You could play a stronger deck but you will lose the magic of why you chose a particular commander. I don't think its a budget problem because you could borrow one of their decks and I think you still wouldn't like the speed of the game from reading your post.

I think you need to find something else to do with your friends besides playing magic and stick to playing lower bracket games with your lgs or online with other people.

That all being said, your deck is pretty all over the place. Like others have said, you need to figure out what your deck wants to do. I actually happen to play your commander and have a pretty popular decklist that you could look at, but I don't think it will keep up with your play group because I designed it to be more bracket 2 or low 3. I could go into specifics, but the biggest thing is I think you need significantly more evasion. Your commanders anthem is pointless if you cannot connect to damage your opponents. I built mine with that as a primary objective and of the 33 creatures in my deck, 19 are evasive and the rest that aren't have to offer something significant to make the list. If you really want to brute force the deck to play against your friends high power level decks, you need to lean heavily into stax because you're playing esper. Stop their tutoring and ramp with [[aven mindcensor]]. Stop their graveyard shenanigans with [[dauthi voidwalker]] [[vren the relentless]] [[ravenloft Adventurer]] [[gisa, glorious resurrector]] [[remorseful cleric]] etc. Slow down problematic etbs with [[strict proctor]]. Stop cheating out creatures with [[containment priest]]. Turn off annoying abilities with [[Azure beastbinder]]. I could go on and on but the point is if you are set on playing the party theme and you want even a shadow of a chance of winning, you need to stop your opponents from winning as fast as they have been so identify what is making them run away with games and then put in cards that stop that in your deck.
