Falco Spara, Pactweaver + Sensei's Divining Top + Toothy, Imaginary Friend + Gran-Gran

Falco Spara, Pactweaver

Sensei's Divining Top

Toothy, Imaginary Friend

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. Toothy 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 uses Falco Spara, Pactweaver to turn your library into a hidden hand, letting you cast spells directly from the top by trading away the creature's counters. Sensei's Divining Top is the beating heart of this loop, drawing you a card and slipping right back onto the top of your library where Falco Spara can immediately reach it. Meanwhile, Toothy, Imaginary Friend sits on the board eagerly collecting +1/+1 counters every time you draw that card, and Gran-Gran patiently sits by ready to filter your hand and potentially discount your noncreature spells if your graveyard holds the right Lessons. By continuously tapping the Top, drawing, and recasting it for zero mana by stripping a counter off a creature, you generate boundless card draw and an endless parade of artifact triggers.
