Kher Keep

A token engine baked into a mana source, which is the whole point: the land never stops making colorless mana, and the second ability gives you somewhere to dump excess red mana once the board has stalled. The Kobold connection runs deeper than flavor. The original Kobolds were a small clutch of zero-cost red creatures from an early-era set, and this is their home base, manufacturing a 0/1 token named after them on demand. That body is almost a non-stat: a 0/1 attacks for nothing and trades down against anything, so the value lives entirely in the count, not the combat math. The land becomes a slow, repeatable spigot of bodies for anything that prices creatures by headcount rather than size: sacrifice fodder, an anthem that turns a pile of 0/1s into a clock, a commander that wants tokens to feed. The throttle is built into the rate. At three mana per token (counting the land's own tap), the engine is deliberately slow, working as a mana sink across a long game rather than a way to flood the board in a single turn. Being a legendary land is the quiet tax on all of this, capping you at one Keep on the battlefield at a time, which is exactly why the token it makes carries a name and a backstory rather than being a generic Kobold: the design treats the Keep and its garrison as a single named fixture, not a repeatable swarm.
