Iron GL

This battle pits Tony Stark with his intelligence and engineering genius is given a ring by the Guardians versus Hal Jordan. Tony has his regular Iron Man armor and 2 days prep to learn how to use the ring.
Battlefield:
Space outer limits of solar system.
Conditions :
KO or Death, no BFR.

I really don't think 2 days is enough. The Sinestro Corps rings have more or less the same capabilities as the GL rings, and it took Mongul 96 hours to learn all the different things the ring could do. Just to learn them, forget about putting that knowledge to practice.
