The colorless source is the disqualifier, and Draftsim's 1/10 is harsh only on tone, not physics. TMT runs on two-color decks with hybrid splashes, and the common fixers (Escape Tunnel, Illegitimate Business, TCRI Building) already claim the tapped, off-color land slots a deck can afford. Northampton Farm adds a third slow source in a deck that wants Mechanized Ninja Cavalry and Foot Ninjas on curve. The format is medium-speed, not slow enough to eat that drag.
The closest home is BG Food, where Anchovy & Banana Pizza and the artifact subtheme already tolerate some clunk, and where flickering an ETB legend twice across separate turns has a ceiling worth chasing. Even there the rate is bad: three mana plus a sacrificed land for one re-ETB and a pile of hand-returns asks the deck to bank creatures under the land first. The exile clause has no timing restriction, so you can stash a creature at instant speed to dodge a removal spell on the stack. That is the one piece of genuine flexibility, and it is also the trap: once a creature sits in exile, Stomped by the Foot and Grounded for Life cannot reach it, but you are spending whole turns assembling the engine while doing nothing to the board.
The real punisher is tempo, not removal. You spend a full turn's worth of mana and a land to return a single body, and the land is gone for good afterward. A deck built on Bespoke Bō beatdown or evasive Sneak threats has no time for that.
Sideboard at best in BG Food or a Mardu sacrifice build with a specific legendary worth the setup. P3 wheel in most pods, zero copies the moment a splash already stretches the mana.
