Falco Spara, Pactweaver + Sensei's Divining Top + Forgotten Ancient + Valeria Richards, Precocious

Falco Spara, Pactweaver

Sensei's Divining Top

Forgotten Ancient

Valeria Richards, Precocious

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. Cast Sensei's Divining Top by paying 0 and removing a counter from a creature you control.
3. Forgotten Ancient triggers, putting a +1/+1 counter on it.
4. Repeat.

This loop turns your library into an endless well of resources by transforming Sensei's Divining Top into a free, repeatable spell. Valeria Richards, Precocious helps grease the engine by making noncreature spells cost less and drawing you an extra card when you start the chain. Meanwhile, Falco Spara, Pactweaver grants you the ability to cast that top card by paying costs with counters rather than mana, and Forgotten Ancient happily absorbs the spells you cast to stockpile fresh counters that keep Falco Spara's payment engine fueled.
