Now, I think Hal will win the majority, even if his "Unlimited Options" Are severely limited by No BFR (Microversing/Ring Universe, etc = BFR IMO)
BUT if there's nothing that Hal can do to keep the Hulk unconscious or Dead for the count, then his Ring will run out and Hulk will win.
Messing with his brain will cause his Healing Factor to compensate.
Going tiny and jumping inside a guy who's immune system has EATEN secondary adamantium isn't smart.
Transmutation? I'm not sure if it's been successfully used on the Hulk, but I'm not even sure if it has even been USED on the Hulk off the top of my head.
Sealing him in something Truly Unbreakable won't be a win.
Sealing him in anything short of Tru Adamantium will allow him to get angry enough to break it, since teh bubbles can keep sunlight out to keep Superman's stressed cells from absorbing more Sunlight, but Hal can't stop him from gettign stronger that way.
GL can drain the Gamma, I'll give him that. But there are more theories that aren't going to work and show a lack of knowledge about the Hulk from people calling others fanboys.
Judge not lest ye be judged.
