How it works

1. Cast Blinkmoth Infusion by paiyng 12, minus 1 for each artifact you control.
2. Kitsa's prowess ability triggers, giving it +1/+1 until end of turn.
3. Holding priority, activate any number of mana-producing artifacts you control, adding at least 2.
4. Activate Kitsa's second ability by paying 2 and tapping it, copying Blinkmoth Infusion.
5. Resolve the copy of Blinkmoth Infusion, untapping all artifacts you control.
6. Repeat from step 3.
