Ranking up

Trying to decide who's the better champ out of these 5

Comments

In general you should always pick 4 stars over 3 stars.

if you're close enough or have one always invest in 5*, but a strong 4* can be better than a weak 5*. I only rank my 5's, personally.

None of the above save your resources for 4 and 5* champs. Only rank up descent 4*
