Tron's mana engine runs on artifacts (Bonder's Ornament, Expedition Map, Giant's Boulder, Barrels of Blasting Jelly), so Dust to Dust is huge for exiling two of their key pieces at once. Sprouting Renewal gives you a flexible answer — either destroy a troublesome artifact or enchantment such as Nyxborn Hydra, which is an enchantment creature, or create a token body when the situation calls for it. This matchup is a straight race against their bigger late-game, so prioritize denying their engine pieces over card selection. Keep the mainboard curve mostly intact since speed is still your primary win condition.
