Aftershock might interest you: still triggers your commander. Burn Trail can trigger multiple times. Staggershock, Flare, and Zap are all efficient as well.

Blaze Commando Is not a legendary creature, therefore cannot be your commander.

xXSarkhavskiXx- Pauper EDH allows you to choose a common or uncommon creature to use as your commander, as I have demonstrated above.

Sorry, I didn't realize this was PAUPER edh.

Rally the Peasants and Gempalm Avenger can give you alpha-strike potential at a very low cost, and Veteran Swordsmith and Armorsmith can give more permanent buffs to your token army. Cool deck!

I like what you've done with it so far! I think it might need a little more burn to really utilize Blaze Commando's ability though. I recently posted my version of this deck. Maybe you can get some ideas. If you have any questions just let me know. Good job though! Blaze Commando Pauper EDH

needs Palace Sentinels and Crown-Hunter Hireling

Wish it said non-combat source, not instants ad sorcery. Would make Impact Tremors so much better. ;)

It'd go infinite lol. Drop Commando, Tremors procs, damages opp, spawns tokens, wash rinse repeat lol. At least they didn't make it where the damage has to go to the opp's face. Then it'd just be garbage.
