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

Scuttling Sliver

Trazyn the Infinite

Unnatural Selection

Timeless 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 Timeless Lotus's ability by tapping it, adding
3. Activate Trazyn by paying 2, untapping it.
4. Repeat from step 2.

This clever loop relies on Trazyn the Infinite absorbing the activated abilities of artifact cards in your graveyard—specifically, Timeless Lotus, which lets Trazyn tap for a full WUBRG rainbow of mana. Because Trazyn also gains Scuttling Sliver's activated ability from the graveyard, it can pay two mana to untap itself infinitely. Finally, Unnatural Selection is the crucial enabler that temporarily turns Trazyn into a Sliver, ensuring the Scuttling Sliver untap ability actually applies to Trazyn in the first place.
