Urza, Prince of Kroog + Corridor Monitor + Empowered Autogenerator

Urza, Prince of Kroog

Corridor Monitor

Empowered Autogenerator

How it works

1. Activate Empowered Autogenerator by tapping it, putting a charge counter on it and adding at least six mana of any color.
2. Activate Urza by paying 6, creating a token copy of Corridor Monitor that is a 1/1 Soldier in addition to its other types.
3. When the Corridor Monitor token enters the battlefield, it triggers, untapping Empowered Autogenerator.
4. Repeat.
5. Once you have infinite mana, you may target any other artifact(s) you control.

This ingenious engine turns a single loop into a self-sustaining wave of creation, fueled by the staggering output of Empowered Autogenerator once it gathers enough charge counters. By sinking that mana into Urza, Prince of Kroog's activated ability, you forge a fresh token copy of Corridor Monitor. Each time that clever automaton enters the battlefield, its triggered ability untaps your Empowered Autogenerator, resetting the mana source so you can repeat the process indefinitely. With the extra mana and Urza's passive anthem pumping your growing army, you end up with infinite colored mana, endless charge counters, and a horde of augmented artifact creature copies ready to overwhelm the table.
