I pulled an epic Manager earlier which gives +13 POW and +13 CHA to your entire deck. That's a pretty sweet deal.
My current set up is this:
2411 W - 330 L
UR++ [Lvl 35] Andre The Giant (482, 527, 407, 500)
UR++ [Lvl 28] Alberto Del Rio (438, 401, 384, 425)
SR++ [Lvl 30] Brock Lesnar (317, 288, 266, 277)
UR [Lvl 30] Shawn Michaels (249, 277, 270, 286)
R++ [Lvl 25] Eva Marie (163, 165, 196, 187)
E Manager (+13 POW, +13 CHA to deck)
SR Second Wind (+9 to all stats)
I'm seriously addicted to this game. But until I start spending money on it I've convinced myself that it's not a problem.
