Knacksaw Clique + Paradise Mantle + Biomancer's Familiar

Knacksaw Clique

Paradise Mantle

Biomancer's Familiar

How it works

1. Activate Knacksaw Clique by tapping it, adding .
2. Activate Knacksaw Clique by paying and untap it, exiling the top card of target opponent's library.
3. Repeat.

This clever loop lets you weaponize your opponent's own library by utilizing Paradise Mantle to grant Knacksaw Clique the ability to tap for mana, paying the exact cost required for its own untap ability. Normally, a tap-and-untap loop on a single creature would be cost-prohibitive, but Biomancer's Familiar steps in to slash the activation cost of Knacksaw Clique's ability down to a single blue mana. Because Paradise Mantle provides the necessary mana through the creature's tap while Biomancer's Familiar discounts the untap symbol, Knacksaw Clique can repeat this process indefinitely to exile every card your opponents own.
