i would cut Daze , Mana Leak and Spell Pierce , they are usually worthless after a few turns. Instead Hinder and Spell Crumple lets you tuck an opposing commander, or perhaps Cryptic Command and Last Word if you dont like tucking in your playgroup. Memory Lapse is just to fun not to have with Daxos. Same goes for Vanishment :)

Field of Dreams and Lantern of Insight lets you choose who has the most valuable card to use.

I would also consider replacing Brave the Elements and Gods Willing with something that protects against boardwipes. Ghostway and Otherworldly Journey for example.

You are heavy on defensive creatures, Blazing Archon Fatespinner Peacekeeper will all do the job better then Windborn Muse and Fog Bank . also lands like Maze of Ith , Mystifying Maze , Prahv, Spires of Order and Kor Haven

In U control Capsize and Cyclonic Rift are imo MVP's and should be includet.

Generelly i found Daxos to benefit alot from manarocks and landfetchers, i would consider stuff like Journeyer's Kite and Gilded Lotus .

Forgot to mention how ridiculously great double strike is on Daxos, now you suddenly have 2 free cards to cast instead of 1. Unless you plan on winning with commander damage, Fireshrieker beats Batterskull .

Just some friendly suggestions ofc :)

Thank you for awesome requests. I will definetly consider some of your requests to improve this deck.

After playing this deck multiple times i noticed that when ever i got Grand Arbiter Augustin IV to battlefield i got a huge advantage from it. I decided to replace Daxos of Meletis with Grand Arbiter Augustin IV and so far it has been a huge success.

PROLIFFERATE You'll need lots of dice is my w/u edh deck check it out

It's really difficult to give an opinion unless you explain what your ideas are for your 100 cards, and writing an explanation might help you rethink the deck yourself! Are there any constraints in terms of meta, theme, budget etc.? Do you have goals for what you want this deck to do? Is there strategies and/or combos involved or does it just contain a lot of good cards? You need to help your viewers before they can help you!
