Jetfire, Ingenious Scientist // Jetfire, Air Guardian + Chromatic Orrery + Doc Samson, Super Psychiatrist

Jetfire, Ingenious Scientist // Jetfire, Air Guardian

Chromatic Orrery

Doc Samson, Super Psychiatrist

How it works

1. Activate Jetfire, Air Guardian by paying 3, converting it and putting four +1/+1 counters on it.
2. Activate Jetfire, Ingenious Scientist by removing all +1/+1 counters from it, adding 4 and converting Jetfire.
3. Repeat.

This loop relies on an ingenious bit of transformer synergy powered by Jetfire, Ingenious Scientist // Jetfire, Air Guardian, which uses its own activated ability to convert and adapt for three mana, netting an extra counter thanks to Doc Samson, Super Psychiatrist replacing counter-placement events with an even larger bounty. Once Jetfire has transformed back into its Air Guardian side with four +1/+1 counters in tow, you can strip those counters away for massive colorless mana—which Chromatic Orrery instantly transforms into any color you desire, letting you pay for the loop's continuous conversion costs while netting infinite mana.
