Looking for opinions on 6* locked champs

DrFunnyguy

With the overflow of catalyst that came my way from the act 6 comp package, I'm going to be upgrading a few 6* locked champs that have gone overlooked on my roster. So I'm looking for some opinions on which ones I should rank up first. The ones I'm thinking about ranking are Aegon, Cassie Lang, Old Man Logan, Toad, Heimdal, Wolverine, Yondu, Wasp & Ghost. Any opinions are appreciated.
