Voltaic Construct + Sanctum Weaver + The Flesh Is Weak

Voltaic Construct

Sanctum Weaver

The Flesh Is Weak

How it works

1. Activate Sanctum Weaver by tapping it, adding at least 3.
2. Activate Voltaic Construct by paying 2, untapping Sanctum Weaver.
3. Repeat

This ingenious loop hinges on turning your mana dork into an artifact creature so it can repeatedly untap itself. With The Flesh Is Weak on the battlefield, your creatures that bear +1/+1 counters—including Sanctum Weaver—are conveniently rendered artifacts in addition to their other types. This status change allows you to pump the {2} activation cost of Voltaic Construct directly into untapping Sanctum Weaver, whose own tap ability yields enough mana to cover the cost and leave you with a growing surplus. Because The Flesh Is Weak also ensures Sanctum Weaver carries that crucial +1/+1 counter from its entry trigger, the weaver is immediately recognized as a valid, untappable target for the construct, fueling an endless engine of colored mana.
