You don't need to even do that, click on allies, then click on the mobage icon on the top right corner (with the white-blue smiley face). You can register, log-out, create a new user.

As for the autobot/decepticon icon/card, that just mean you haven't obtain the card. You don't have to get them, but those are usually the rare card/weapon ... you can get them later.
