One Two Three Four Five Six. So they kind of took something that would have been really awesome and made it horrible. First, ew ugly art. Out of all of that, there's only one or two panels that I'd like to add to my icons.
Aesthetics aside, I think it'd...actually be pretty cool for Dr. Strange to take Billy under his wing and shape him up to be the next Sorcerer Supreme. I'm pretty sure it won't happen, especially with Marvel's latest craze of "let's give all the power to the BAD GUYS." But it'd be cool. If Marvel had the patience to do a cute master/apprentice thing.
But really guys, Billy is smarter than to walk around in his civvies while wearing his cape.
Also, lightning is about the only magic Billy can consistently do without an incantation. And Billy doesn't need a Cloak of Levitation. He does it automatically when spellcasting whether he wants to or not. Pay attention to the source material, writers.
(Added note: Wiccan also doesn't appear in any of the official speculation, so yeah. I feel like I just got baited.)
