So this is a pared-down version of a 5-color Big Dumb Dragons deck I put together on MTG Arena. The original deck did very well when it fired, but was clunky and a but unreliable. To fix that, I dropped White and Blue and focused more on interactions between the Jund colors.

The basic idea is to throw out a lot of early-game threats that are small, but too dangerous to ignore, while slowly building the mana base to start playing humongous dragons in the late game. I'm posting the deck list here because I HOPE y'all can give me some suggestions to streamline and optimize the build. Some of the choices are dictated by what I have on Arena, but I'll take any ideas I can get!

This is the exact list I'm currently using, and once again, I am asking for comments and suggestions.
