Win PVP Prize
Hey guys, tired of missing out on the PVP prize because you are short a few energy? Well as long as you beat the 1st four, you can enter the fight confirmation screen. Once there just put your device down and go goof off for however long it is that you need to get 5 PVP energy. Comeback and you will still be in the fight screen, hit the fight button and you will still win the prize if you win. Oh no, you lost that last fight for a fire booster... well dont hit continue, just go goof off for another hour and a half. Fight later from where you left off and boom nice shiney prize.
Probably not a good strategy if you want to climb PVP leaderboard but hey, if you are sitting on 7 Ming Yao's this will come in handy.
