This clever loop turns your mana dork into an engine of infinite green mana by leveraging the first chapter of Phyrexian Scriptures to permanently transform Priest of Titania into an artifact creature. Once she wears that machine-like shell, Voltaic Construct steps in to systematically untap her for the low cost of two mana, a fee easily paid down by the massive influx of green mana generated by Priest of Titania as long as you control enough fellow Elves. The rest of Phyrexian Scriptures' saga chapters simply hang in the background as a ticking clock, but it's that crucial type-changing first chapter that opens the door for Voltaic Construct to bridge the gap and achieve absolute mechanical synergy.
