Actually, if you add in the value of all the covers you're not selling in order to level the champion, you get *EXACTLY* your investment back.

Upgrading a 2-star to champion costs 5000 Iso-8. 2-star covers are valued at 250 Iso-8, so 50 2-star covers add up to 12500 Iso-8.

Total cost: 17,500

Total return: 17,500

This holds for 3- and 4-star champions, as well. I'm not certain on 5-stars because I don't know what a 5-star cover's value is (can't find that data on the wiki anywhere).
