Standard UR Tron deck

Around the Kamigawa/Ravnica Standard, a Urzatron deck packing cards like Meloku, the Clouded Mirror and Keiga, the Tide Star made quiet an impact. The deck revolves around stalling the early game while playing a good amount of cantrips and card draw until you assemble the full "Tron" (Urza's Tower, Urza's Mine and Urza's Power Plant). Reaching that point you'll have a resource advantage so large that losing the game is a minor possibility.
