Kiora, Behemoth Beckoner + Displacer Kitten + Isochron Scepter + Oath of Teferi + Sol Ring

Kiora, Behemoth Beckoner

Displacer Kitten

Isochron Scepter

Oath of Teferi

Sol Ring

How it works

1. Activate Sol Ring by tapping it, adding CC.
2. Activate Kiora's loyalty ability twice by removing two loyalty counters from it, untapping Sol Ring and Isochron Scepter.
3. Activate Isochron Scepter by paying 2 and tapping it, casting a copy of the exiled card without paying its mana cost.
4. Displacer Kitten triggers, blinking Kiora.
5. Resolve the copy of the instant card.
6. Repeat.

This intricate loop spins into motion thanks to Sol Ring, which provides the raw colorless mana needed to fund Isochron Scepter's ability to repeatedly cast the instant spell trapped within it. Every time you cast that noncreature spell, Displacer Kitten triggers to blink Kiora, Behemoth Beckoner, resetting her loyalty and allowing you to leverage Oath of Teferi's static ability. Because Oath of Teferi lets you activate a planeswalker's loyalty abilities twice per turn, a single reset Kiora can immediately use her minus ability twice to untap both your mana source and your imprint artifact—drawing a card along the way thanks to Kiora's own passive triggered ability whenever a creature with power 4 or greater enters (or in this case, simply feeding your engine with endless card advantage and storm count).
