Magus Lucea Kane + Pili-Pala + Agatha's Soul Cauldron

Magus Lucea Kane

Pili-Pala

Agatha's Soul Cauldron

How it works

1. Activate Magus Lucea Kane by tapping it, adding CC and copying the next spell you cast or ability you activate with X in its mana cost.
2. Activate Magus Lucea Kane using Pili-Pala's ability by paying 2 and untapping it, adding one mana of any color.
3. Repeat.

This ingenious engine comes together by feeding Magus Lucea Kane's activated ability into a self-sustaining mana loop. By exiling Pili-Pala with Agatha's Soul Cauldron and placing a +1/+1 counter on Magus Lucea Kane using that same Cauldron, you grant the Magus the untap-and-mana ability of Pili-Pala. Thanks to Agatha's Soul Cauldron's color-filtering text, you can easily pay the required costs to continually untap and generate mana, which in turn fuels an infinite storm of copied spells and abilities with {X} in their costs.
