Eastfarthing Farmer isnt powerful enough of a card to normally make it in a Commander deck, but because its a Halfling that cares about Food, and because the artwork looks a lot like my friend Shivam Bhatt from the Commander Advisory Group, its got a place in the deck, especially since I have a foil copy
However, what may surprise you is the minuscule difference between this card and the Ultra Rare from the same set

This and its lesser-known counterpart Phyrexian Walker can be found turboing out affinity creatures like Myr Enforcer, turning on Mox Opals and picking up a turn two Colossus Hammer in Modern
