Sensei's Divining Top + Shabraz, the Skyshark + Bolas's Citadel

Sensei's Divining Top

Shabraz, the Skyshark

Bolas's Citadel

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. Shabraz triggers, causing you to gain 1 life and put a +1/+1 counter on Shabraz.
3. Cast Sensei's Divining Top from the top of your library by paying 1 life.
4. Repeat.

This elegant engine turns a modest artifact into a perpetual motion machine by leveraging Bolas's Citadel to cast spells straight from the top of your library using life instead of mana. You simply tap Sensei's Divining Top to draw a card and place it back on top of your library, and because Bolas's Citadel lets you recast it for a mere 1 life, the cycle becomes self-sustaining. Meanwhile, every iteration feeds Shabraz, the Skyshark's triggered ability, rapidly growing the shark into a colossal threat while netting you infinite life and card draw.
