Just bought BOB from the Matrix Site. I've downloaded both patches V1.15 and V1.16. Do I need to install Both of them sequentially or is V1.16 all inclusive and is all I need? Thanks.

I seem to have forgotten how to use the BattleCards when fighting on the battlefield. I didn't find the answer in the manual. I also can't remember it from the tutorial. Can someone tell me how it's done?
Thanks, and BTW, I love this game!
