My goal with this list was to coagulate all the commanders that were not strictly worse than other cards for the pauper commander format. Let me know what multicolored cards I missed or what I mislabeled as of now. Thank you!

other ideas without a dedicated slot:

Allies

storm? can you in singleton pauper?

dumb combo Kathari Remnant

Check out the guildmages. Seems like a nice value engine. take a second pass at the guildmages here (http://magiccards.info/query?q=guildmage+r%3Auncommon&v=card&s=cmc)

Korozda Guildmage seems to have a lot of play as tokens, reanimator, ramp, voltron, etc.

Simic Guildmage does things. see if those things work.

Marrow Chomper . No idea where to sort him. Tokens? voltron? meh

Qasali Ambusher is cool. Rules note: Using the ability does not avoid command tax

Marchesa's Smuggler is a card I think is cool, so I put it here. Probably isn't good, but whatever.

Juniper Order Ranger can do a bunch of things pretty well. tokens, voltron, beatdown.

Kulrath Knight wither control sounds neat

Inkfathom Witch for something... Unblockable tribal?

Ascended Lawmage . Don't underestimate hexproof in a world without good wraths.

Wood Sage for graveyard stuff and control. could be neat.

Army Ants land destruction. maybe for 1v1 games, but not much else otherwise

Gilder Bairn probably works best with +1/+1, but there are other counters in pauper too.

Check out the hatchlings here (http://magiccards.info/query?q=hatchling+r%3Duncommon+t%3Aelemental&v=card&s=cmc)
