Nine generic mana with no colored requirement makes this castable in any TMT deck on paper. The format mostly does not get there. The common curve tops out at five and six, and there is no ramp at common to speed the climb: Food exists for chip lifegain and sacrifice fodder, not mana. Eight mana is the realistic ceiling a deck plans around; reaching nine usually means the game has already tipped in one direction or the other.
The body is the entire pitch, and it is the reason the card is not a trap. A 9/9 with flying, trample, indestructible, and haste ends a game on its own, no board required. The anthem clause that hands the same package to your other artifact creatures is real upside when an artifact board survives to the cast, but TMT's removal is medium-density and evenly spread (Stomped by the Foot, Grounded for Life, Dimensional Exile), so the supporting cast has usually been thinned by the time you untap with nine lands. Treat the anthem as a bonus, not the plan.
What turns this from a curiosity into a build-around is Sneak, the set's defining mechanic at fifty-nine cards. A UR or Grixis artifacts shell can put Krang onto the battlefield without paying the cost, swing for nine in the air, and ignore the empty field entirely. The competition for that finisher slot is the set's mythic Turtle legends and Shredder, Unrelenting, all bombs that cost far less and never ask you to also assemble a cheat engine.
Hard-cast, this is a P1P8-or-later hold that rarely makes the maindeck. As a Sneak payoff in a dedicated UR artifacts build, it is a deliberate late-pick reward worth the detour.
