Ironhide is all about defense. if he survives round 1, he WILL survive round 2. If he is in front of other tanks, or if you are facing allot of front row attackers, he kills their attacks leaving you more room to counter attack. Ironhide also has a synergy with Sideswipe, so there is that bonus too.

Motormaster is a better "pure" tank.

Otherwise, those cards are good for now. Replace Bumblebee with your next S card that fits. After that, you will be in the position to really start evaluating skills. For example, if you get starscream, then buff sunstorm. If you get moonracer, replace red alert.
