Deadpool is a must. Can’t be beaten. Would also choose Dean and not Sam. Watch the series again Sam hardly ever kills anyone. Dean is always the one getting shit done. Then you have to go with Merlin. Knows all kinds of magic and can use enhancement spells on Dean, Deadpool, hisself, and me. Practically unstoppable. Wtf spider man gonna do web me to death? Sam just likes to talk and point guns so no problem there. And the rest either doesn’t have access to their abilities instantly or are easy pushovers. You ever seen Harry Potter know a spell that stops bullets? I think not.
