Best 2 star second member with Classic Storm

Unknown

I have a 5/5/3 classic storm at lvl 61. Long term, who makes a better match with classic storm? I am thinking 2 star wolverine or 2 star Thor. I have both of them, but I am missing several covers for both. Which one should I invest ISO into more heavily? I am leaning towards Thor even though he is only 1/1/2 at the moment. For a third I usually have a mid leveled Venom or 1 star black widow, but after the avenger tournament I am leaning towards dark avenger widow for better color coverage. Any other delicious combinations out there that I have not mentioned?
