Falco Spara, Pactweaver + Sensei's Divining Top + Vodalian Wave-Knight + Cemetery Prowler

Falco Spara, Pactweaver

Sensei's Divining Top

Vodalian Wave-Knight

Cemetery Prowler

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. Vodalian Wave-Knight triggers, putting a +1/+1 counter on each other Knight and/or Merfolk you control.
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 loop turns the top of your library into an endless engine, fueled entirely by the synergy between Sensei's Divining Top and Falco Spara, Pactweaver. While Sensei's Divining Top normally trades itself for a card and returns to the library, Falco Spara, Pactweaver lets you recast it directly from the top by stripping away a counter instead of paying its mana cost. Meanwhile, Vodalian Wave-Knight provides a steady supply of new counters to feed this habit every time you draw, and Cemetery Prowler works quietly in the background to ensure those casts happen for free by reducing the cost of artifacts down to zero.
