Scuttling Sliver + Trazyn the Infinite + Unnatural Selection + Gilded Lotus

Scuttling Sliver

Trazyn the Infinite

Unnatural Selection

Gilded Lotus

How it works

1. Activate Unnatural Selection by paying 1, causing Trazyn to become a Sliver until end of turn.
2. Activate Trazyn using Gilded Lotus's ability by tapping it, adding three mana of any color.
3. Activate Trazyn by paying 2, untapping it.
4. Repeat from step 2.

This clever engine transforms Trazyn the Infinite into an infinite mana generator right from your graveyard, leveraging the artifact text-copying power of Prismatic Gallery. By using Unnatural Selection to temporarily turn Trazyn into a Sliver, you grant him Scuttling Sliver's activated untap ability. With Gilded Lotus resting in the graveyard alongside them, Trazyn can tap for three mana and pay just two to untap himself, netting positive mana on every single loop.
