Scuttling Sliver + Trazyn the Infinite + Unnatural Selection + White Lotus Tile

Scuttling Sliver

Trazyn the Infinite

Unnatural Selection

White Lotus Tile

How it works

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

This loop relies on Trazyn the Infinite absorbing the activated abilities of your graveyard's artifacts, specifically granting itself the mana-producing capabilities of White Lotus Tile. To make the math work, Unnatural Selection steps in to manipulate creature types, letting you pay {1} to temporarily make Trazyn a Sliver so that it shares a type with Scuttling Sliver. Once that shared type is established, White Lotus Tile can tap for three mana, easily covering the {2} untap cost granted by Scuttling Sliver's ability and leaving you with infinite colored mana.
