Guys can you give me suggestions to which champions to upgrade.

Of those, focus on archangel

I need 5 champions

Can you give rank based on available heroes?

Archangel, black panther, spider man and doc oc

Archangel Doc. Oc Spiderman Civil warrior black panther. In that order. DOC OC takes a bit of practicing but eventually very rewarding.

Do you need to upgrade 5 Immediately? I'm sure you'll open better 4*s soon

Hmmm ok thanks
