This clever loop transforms Trazyn the Infinite into a mana-generating engine by borrowing activated abilities from the graveyard and battlefield. With Dreamstone Hedron sitting in the graveyard, its mana-producing ability is stolen by Trazyn thanks to Prismatic Gallery. Meanwhile, Imagecrafter temporarily makes Trazyn a Sliver, allowing you to use Scuttling Sliver's native static ability to grant Trazyn the ability to untap itself for just two mana. By tapping Trazyn for three colorless mana and spending two of them to untap it with Scuttling Sliver's rule, you generate an endless surplus of colorless mana.
