Banker Tryndamere beats you to death with a fat sack of gold!
Title probably says enough but the idea is you start with a droopy empty sack with a dollar sign and the more gold or more AD you get the fatter it gets and the more it hurts when tryndamere beats you over the head with it. Eventually it could start leaking money when you spin to add some visual flair.
Comes with sweet black suit maybe a gold/white/purple pimp suit with zebra fur chroma and a make it rain dance for maximum bm. This would sell. This would sell lots.
