Teferi, Temporal Archmage + Displacer Kitten + Clockspinning

Teferi, Temporal Archmage

Displacer Kitten

Clockspinning

How it works

1. Activate up to four permanents by tapping them, adding at least 3.
2. Cast Clockspinning with buyback by paying 3.
3. Displacer Kitten triggers, blinking Teferi.
4. Resolve Clockspinning, returning Clockspinning to your hand.
5. Activate Teferi's second loyalty ability by removing a loyalty counter from it, untapping up to four permanents.
6. Repeat.
7. If the four permanents can tap to produce at least 3, you may get infinite mana, and then use Teferi's first loyalty ability instead.
