The activation cost is the whole argument. Five mana for a Shock that leaves a 1/1 behind is not a rate that wins a midrange format on its own, and TMT is a midrange format: medium speed, medium removal, common creatures sitting at the 2/3 and 3/2 bands that a three-damage activation answers cleanly but a 1/1 Robot cannot threaten. Draftsim's 3/10 is too low, but the diagnosis underneath it (no obvious sacrifice outlets at common) is right. Without a second engine in the room, the card is a slow two-for-one: you cast it for a token now and pay a full turn later to get the back half.
The home is BR or Mardu Sacrifice, where the Food subtheme gives the Foundry somewhere to be cashed in before turn five. Anchovy & Banana Pizza and Omni-Cheese Pizza are the throughput it wants: a token to feed, a Food to convert, and a steady drip of artifact-count triggers that the activated removal feeds back into. In a base-red deck without that scaffolding, it sits as a P1P8-to-P1P12 flex card that you maindeck two of and quietly regret.
In committed BR Sacrifice the band climbs to P1P5 to P1P7, still behind Bot Bashing Time and Stomped by the Foot as raw removal, but a real engine piece once you've signaled. Bespoke Bō and Novel Nunchaku turn the spare Robots into a clock, which is what keeps the five-mana activation honest. The failure case is drafting it on text in UR Sneak or RW Equipment, where you never want to spend the turn to fire the leave trigger and the front-loaded 1/1 is all you ever get for your two mana.
