This list is entirely arbitrary.
Clan tags whose image is difficult to decipher were eliminated automatically.
Here are the top ten:
3: Young Money Cash Money Billionaires
4: Coalition of Role-Playing Friends
5: The Clan of Warlighters
8: League of Erroneous Aspirations
9: Warlight Masters
10: The Red Eagles
The rest of you clans should probably find something more impressive if you want your clan tag to strike fear into the hearts of mortals.
