There are only two ways the game can go after putting R5 Optimus & Megatron out there: either the game is over, or R6 cards are coming. So all you folks who have spent and are spending the big bucks on these R5s... get to do it all over again for R6 cards. Bend over & open your wallet.

And Mobage introduced R6 to Blood Brothers not two weeks ago.
