Sensei's Divining Top

Oneirophage

Gran-Gran

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. Oneirophage triggers, putting a +1/+1 counter on it.
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.

This clever engine transforms Sensei's Divining Top into a free, repeatable card draw machine by looping it directly from the top of your library. Falco Spara, Pactweaver enables this loop by letting you cast spells off the top of your library using creature counters as an alternate payment, seamlessly bypassing the Top's normal mana cost. Meanwhile, Oneirophage capitalizes on every single iteration by growing larger with every card drawn, turning your infinite draw triggers into a massive flying threat. Gran-Gran sits on the sidelines, though its presence is accounted for in the deck's infrastructure while the primary loop effortlessly spins the Top back onto your library over and over again.
