Tron relies heavily on artifacts like Barrels of Blasting Jelly, Bonder's Ornament, and Expedition Map to fix mana and ramp, so Steel Sabotage can counter these key artifact spells or bounce them to slow the deck down. Nihil Spellbomb doesn't interact with their gameplan directly since Tron isn't graveyard-based, but it can exile a graveyard if they use Pulse of Murasa or Crop Rotation loops incidentally, though its main value here is minor; consider it a low-impact inclusion. Abandon Attachments and Spell Pierce are cut since Tron's ramp quickly outclasses tempo plays and Spell Pierce's tax is trivially paid once they hit their extra Tron lands.
