Butterbur, Bree Innkeeper

The condition on the trigger is the whole design: not "create a Food each turn" but "create a Food if you don't have one." That single word turns a passive generator into a self-throttling one, guaranteeing exactly one Food in reserve rather than a stack of them. It refills on your next end step after you cash a token in but never overfills, which is a deliberate choke on the Food-matters engines that would otherwise treat unconditional token generation as free fuel. What you get is a steady drip: one Food replenished each end step you don't already have one, so any payoff that wants to sacrifice Food (aristocrat drains, artifact-count triggers, lifegain-matters shells) has a reliable trickle to work with rather than a flood. The 3/3 body is beside the point; this is a support piece dressed as a creature, an engine that asks the rest of the deck to convert its output into something that closes games. The flavor lands cleanly, too: an innkeeper who keeps a single loaf on the counter and bakes another once it's gone. As a green-white value builder the card is unusually disciplined, refusing to hand you more resource than you can immediately use, which makes it a better fit for decks that want a guaranteed sacrifice fodder loop than for decks trying to go wide on artifacts as fast as possible.
