Sensei's Divining Top + Sheoldred, the Apocalypse + Gwenom, Remorseless

Sensei's Divining Top

Sheoldred, the Apocalypse

Gwenom, Remorseless

How it works

1. Activate Sense's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library from the battlefield.
2. Sheoldred triggers, causing you to gain 2 life.
3. Cast Sensei's Divining Top from the top of your library by paying 1 life.
4. Repeat.

By tapping Sensei's Divining Top to draw a card and place itself back on top of your library, you set up a smooth self-sustaining loop. The presence of Sheoldred, the Apocalypse turns that card draw into a net gain of 2 life, cushioning the cost to keep things moving. Meanwhile, Gwenom, Remorseless lets you cast the Top directly from the top of your library by paying 1 life instead of its mana cost, allowing you to replay it and start the process all over again.
