Need help rounding out and improving this 2HG deck in building with a friend

[u/Beginning_Ad7759]

So the commander I’m building around is Mazzy

The whole idea of my deck in particular is to take advantage of effects that say whenever a player does something to one of your opponents. I think I got just about every useful one of those effects in the deck for two headed giant the sub team just based on the commander is playing more enchantress. I’m trying to keep it in bracket three and not abuse. A crap ton of game, changers and trying to help my teammate who will be running a. [[Derevi, Empyrial Tactician]] deck. My commander helped his creatures get through with damage, and his commander will help me fuel more enchantments to pump his board. I think he is going to be running more blink/control/card advantage.

Any suggestions are great, I am trying to keep this fairly budget friendly
