"Epic Matching?"

Well... you see, there's a problem when I play Epic PVP. The game keeps putting me with people much more powerful, for here's an example: 1. Banner Health (me): 7999 Birds: Bard, 1090, Samurai, 1500, Spies 997 2. Banner Health (other person): 10800 Birds: SeaDog, 1800, Paladin 2,480, Bard, 1,600 What?! How? My league: Iron Their league:Diamond Result: LOSE! Is that supposed to be normal? And when I put up my best classes for my birds to fight, they somehow STILL get defeated! Can you please tell me why they match like this and some good bird combos?
