I like building random Brawl decks on Arena (if you're not familiar with Brawl, it's like Commander but 1v1 on Arena). I like tribal decks and I recently made Phyrexian tribal with Atraxa, it's working ok so far but I think it could be better. I feel like it needs a more consistent way to get and build up poison counters besides just Atraxa herself.

I'll also share a few more decks I've made to get some more discussion in here. Advice is welcome but I am a bit low on rare/mythic wildcards to craft new stuff.

Atraxa Phyrexians

Prismatic Bridge Angel tribal

Krydle Rogues/Ninjas

Imoti

Nissa combo
