Barry ( Triumphant Light ) reduces the attack costs of each Staraptor, Heracross, and Snorlax you control by 2 Colorless Energy for a turn
Like U/G, going this route essentially sets you up to play generic good stuff control, so avoid playing the risky madness/delirium cards and prioritize bombs, removal and value like Said // Done that will help grind opponents into dust
This is a method that WotC repeatedly recommended to all users complaining of the invalid command line error
The instant and sorcery spells in this deck could also use some refinement
If you target itself with its ability and land combat damage, you can draw 15 cards
The heavy reliance on Artifacts means that Urza gets exceptional value from Stax cards such as Stasis and Winter Orb, since you will not be as reliant on Lands as most other decks
