I just started playing commander a few weeks ago and have started working on building my own decks. I was hoping to get some insight from some more experienced players as to how to improve them. My friends are many things, helpful is not one of them lol.

Birbs. Tempest hawk focused
Birbs • (Azorius Commander deck) • Archidekt

This Eruth spell slinger deck
Phantom Particle • (Izzet Commander deck) • Archidekt

Zombie deck
Rise • (Dimir Commander deck) • Archidekt

Any insight is appreciated, as i've kind of hit a wall with my own knowledge.
