Voltaic Construct + Phyrexian Scriptures + Accomplished Alchemist

Voltaic Construct

Phyrexian Scriptures

Accomplished Alchemist

How it works

1. Cause Accomplished Alchemist to become an artifact using Phyrexian Scriptures.
2. Activate Accomplished Alchemist by tapping it, adding at least 3.
3. Activate Voltaic Construct by paying 2, untapping Accomplished Alchemist.
4. Repeat from step 2.

This clever loop transforms Accomplished Alchemist into an artifact creature using the first chapter of Phyrexian Scriptures, setting the stage for Voltaic Construct to untap it for just two mana. As long as you have gained enough life this turn for Accomplished Alchemist to tap for three or more mana, you will generate a net surplus on each iteration. This leaves you with an infinite supply of colored mana to fuel the rest of your game plan.
