Based on description it seems like there may be two reasons for your commander. You like artifacts, in which case you have pretty much the best blue commander for cheating them out. The other is maybe you just plain like circumventing mana costs. For the latter Braids, Conjurer Adept is better, though EXPENSIVE to build around since she encourages just an army of supers combined with steal and clone cards. Just an idea, there's a deck of her on my profile if you want to see how it may work properly, otherwise solid deck and +1 and I'll be on later to recommend artifacts for Muzzio.

yeah the reason i don't really play braids is because i personally have absolutely blew someone out when they played it and i really just don't like that it gives everyone else free drops. and really this deck is all about artifacts it was based off a modern deck that i used to have that was just about getting out big stompy artifact creatures and i really loved it so i made it into an edh deck so it would work better

What about Chief Engineer? Convoke to all artifacts can get the ball rolling pretty fast

Haha, yeah Braids is interesting to run. Like I said she's pricey to build around but is beast when done right. She backfires though if you try to put a budget on her so I can imagine you smashed face.

As for artifact suggestions I'd add in maybe a Sword of Fire and Ice or a Sword of Body and Mind. These add some decent utility as well as allowing a decent set up into dropping a large creature later in the game. Etched Champion may be small, but the protection combined with being colorless will severely impair most voltron decks. Inkwell Leviathan is great with Muzzio as well.

so i was considering Chief Engineer but it just seems too slow for the deck i haven't yet tried it out but i have been thinking about running it at least to try it out. now Sword of Fire and Ice is something that i have been looking for but if i get one it's going into my animar deck so if i happen to be able to trade for two then hell yeah, Sword of Body and Mind i don't really see how it would be good in this deck besides the protection. i actually forgot completely about Etched Champion so that's going in and i have an Inkwell Leviathan in my animar deck and it's surprisingly hard to find it so if i find one it will be going in.

Crystal Ball is a cool combo, scry two, then muzzio what you kept on top

Void Stalker better than Gomazoa?

Vortex Elemental even better, as it can get two creatures if you ramp hard enough

I recommend Illusionist's Bracers because you use Muzzio's ability twice when it's equipped to him and its an artifact :)
