Sensei's Divining Top

Vodalian Wave-Knight

Stone Calendar

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 engine transforms the top of your library into an endless revolving door for Sensei's Divining Top, letting you tap it to draw a card and slide itself right back onto your library. Thanks to Falco Spara, Pactweaver letting you cast spells from the top of your library by consuming creature counters as an alternate cost—while Stone Calendar drops that casting cost down to zero—you can continuously replay the top artifact without spending any actual mana. Meanwhile, Vodalian Wave-Knight watches every single card draw happen and cascades a growing tide of +1/+1 counters across your board to continuously refuel Falco Spara, Pactweaver's counter-economy.
