Noob question; What are the symbols in right upper corner ?

I didn’t find anything in the sub list that would help me with this, so it’s confusing that a two different Attack Champs can have completely different symbols? I’ve created a list of champions, and rate them from 3* and up ! My accounts officially 81 days old today, so I think I’m doing the right things ? I use a the two flags for HP, Support for Support, Defense for Defense,and Hearts for any 3* and up ! However I keep seeing these symbols, and they’re on different types of champions, so I’m kinda confused about there exact meaning ? Any help would be great appreciated.
