Falco Spara, Pactweaver

Sensei's Divining Top

Shabraz, the Skyshark

The Immortal Sun

How it works

1. Activate Sensei'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.
2. Shabraz triggers, putting a +1/+1 counter on it and causing you to gain 1 life.
3. Cast Sensei's Divining Top from the top of your library by paying 0 and removing a counter from a creature you control.
4. Repeat.

By letting you cast spells directly off your library using creature counters as an alternate cost, Falco Spara, Pactweaver turns Sensei's Divining Top into a self-sustaining loop; you simply tap the Top to draw itself and place it back on top, then recast it for free by stripping a counter away. While this engine cycles endlessly, The Immortal Sun pulls double duty by making those Top casts completely free with its cost reduction while boosting your board, and Shabraz, the Skyshark capitalizes on every single cycle to grow infinitely large and drain life from your opponents.
