Idea for mastery 6 and 7

mastery 6: unlocked after: gaining 10 S ranks and 100K mastery points with said champ reward: champion's icon for summoner's icon

mastery 7: unlocked after: gaining 30 S ranks and 500K mastery points with said champs reward: champion's skills' icon for summoner's icon

just a simple idea [slayer-jinx-wink]
