Urza, Powerstone Prodigy

Gameplan

Use Urza's loot ability each turn to dig and pitch artifacts, generating Powerstone tokens that ramp into big artifacts and colorless mana. Build a mono-blue artifact engine that snowballs into either a powerful payoff (big creatures, draw engines) or an artifact-based combo, then close with overwhelming card advantage and ramp.

Key Cards

• Mind Stone — Cheap mana rock you can pitch to Urza for a Powerstone or cash in for a card late.
• Foundry Inspector — Cost reduction stacks with Powerstone ramp to deploy multiple artifacts per turn.
• Thopter Spy Network — Turns your artifact density into a recurring token and card-draw engine.
• Karn, the Great Creator — Stops opposing artifact abilities and tutors any artifact from outside the game.
• Sai, Master Thopterist — Generates flyers and card advantage whenever you cast artifacts.
• Unwinding Clock — Untaps Powerstones and artifacts on each turn, doubling your colorless output.
• Brudiclad, Telchor Engineer — Can copy a token to turn your Powerstones into an army (in the 99 of similar shells, but here as inspiration—note color).

Upgrade Path

Add fast mana rocks (Sol Ring, Mana Crypt, Mana Vault) and cost reducers to accelerate Powerstone synergy, then layer in a compact combo finish like Time Sieve plus token engines or infinite-mana into an artifact outlet. Improve interaction with premium counterspells (Mana Drain, Fierce Guardianship, Force of Negation) and tutors like Transmute Artifact and Whir of Invention to find your payoffs consistently. Finally, include artifact recursion (Goblin Welder analogs, Academy Ruins) to make discarding artifacts to Urza pure upside.
