@soothing_sounds: because your having him use equipment that he has never used before so it's never been part of his character, whereas if IM and Apoc have used it it's part of there's. Something that's not recommend in the vine rules.
Sort of along the lines of giving a Batman a green ring which would have hypothetical results vs giving Luthor an orange which he has actually wielded.
Except Hulk has used celestial equipment before and Banner's just using a different type of resource. I already said there was slight speculation and i apologized for it.
@dextersinister: No. Hulk using Banner prep with Celestial tech as a resource is not the same as fighting Apoc & IM. I don't know how that could be similar in any way except that they're sharing the same pool of resources. How is Hulk, infinite creature of strength related to the tech guy and the first mutant.
@lvenger: He doesn't, but there have been many times Hulk has used celestial tech as well as multitudes of times Celestial tech has been worked on by other genius's. Slight speculation, i know, i apologize.
