Sensei's Divining Top + Voyager Quickwelder + Rook Turret

Sensei's Divining Top

Voyager Quickwelder

Rook Turret

How it works

1. Cast Sensei's Divining Top by paying 0 due to Voyager Quickwelder.
2. When Sensei's Divining Top enters, Rook Turret triggers.
3. Holding priority, activate Sensei's Divining Top by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
4. Resolve the Rook Turret trigger, causing you to draw Sensei's Divining Top from your library, and then discard a card other than Sensei's Divining Top.
5. Repeat

This clever loop turns the unassuming artifact engine into an endless card-filtering machine. While Voyager Quickwelder discounts your artifact spells to make casting Sensei's Divining Top completely free, Rook Turret provides the vital payoff by turning every entry of the Top into a forced draw and discard. Instead of just letting the Top resolve normally, you tap it in response to the Rook Turret trigger to draw a card and tuck itself safely on top of your library, where the Rook's resolution then draws it right back into your hand.
