Scuttling Sliver + Trazyn the Infinite + Psychic Paper + Arc Reactor

Scuttling Sliver

Trazyn the Infinite

Psychic Paper

Arc Reactor

How it works

1. Activate Trazyn using Arc Reactor's ability by tapping it, adding CCC
2. Activate Trazyn by paying 2, untapping it.
3. Repeat.

This clever loop turns Trazyn the Infinite into a self-contained mana engine by borrowing abilities from the graveyard and the battlefield. Because Trazyn's Prismatic Gallery grants it all activated abilities of artifact cards in your graveyard, having Arc Reactor down there lets Trazyn tap itself for three colorless mana. Meanwhile, Scuttling Sliver grants all your Slivers—including Trazyn, since Psychic Paper has made Trazyn a Sliver (along with whatever name and creature types you chose)—the ability to untap for just two mana. By spending two of the three mana generated by the Arc Reactor ability to pay Scuttling Sliver's untap cost, Trazyn can endlessly repeat the process to generate infinite colorless mana.
