I think the simplest, and sadly the most uninteresting, is to cantrip your commons;
Made him colour flexible, you can run all of the bad pauper colours but needs to focus around white as I feel that is the best colour "for the common folk".Fiador, Marshal of the Masses
Creature - Legendary Human Soldier
Eminence - As long as Fiador is in the command zone or on the battlefield, you cannot cast spells not of common rarity.
When Fiador enters the battlefield, choose green or red. Whenever you cast a common creature spell that is white or the chosen colour, draw a card.

His eminence ability restricts you to commons at all times, but you will only benefit from the draw if he is in play and with a creature heavy strategy. Deck would likely run as a mass of crappy peasants and then some bad spot removal or overruns.
Trying to make a weird izzet spellslinger deck, one that rewards you for having a mixture of the two colours instead of just the powerful blue commons.Sorlis, Half-mad Alchemist
Creature - Legendary Fairy Wizard
Eminence - As long as Sorlis is in the command zone or on the battlefield, you cannot cast spells not of common rarity.

Whenever you cast a red spell, reveal the top card of your library. If that card is a blue card, Sorlis deals X damage to itself and X damage to any target, where X is the CMC of the revealed card.
Whenever you cast a blue spell, reveal the top card of your library. If it is a red card, put it into your hand.

I'm trying to capture the idea of a mediocre necromancer, who can raise the dead but not keep them going.Akisk, Apprentice Necromancer
Creature - Legendary Human Wizard
Eminence - As long as Akisk is in the command zone or on the battlefield, you cannot cast spells not of common rarity.
Flying
Whenever a non-zombie creature you control dies, create a token that is a copy of that card, except that it is a black zombie instead of its other colours and types.
At the beginning of your end step, sacrifice all zombies you control with a decay counter on them. Then, put a decay counter on each zombie creature you control.

Wondering if the nexus community has some pauper commander ideas they can contribute? Can we make these cards interesting in some way?
