44. Should have 2 more by the end of the week due to all the IP I just got. Still don't own Yi because I hate playing him.
Edit: I think I've only used RP on 3 champs, one of which was Elise in her bundle because I like the skin. So yeah, just get your first win everyday and in a few months, you'll have plenty of champs to work with.
