Six characters were revealed so far: Optimus Prime, Autobot Leader / Optimus Prime, Hero Goldbug, Scrappy Scout / Goldbug, Humanitys Ally Starscream, Seeker Leader / Starscream, Power Hungry Soundwave, Superior Captain / Soundwave, Sonic Spy Flamewar, Streetwise Operative / Flamewar, Brash Veteran Slicer, High-Speed Antagonist / Slicer, Hired Muscle There will be 15 double-sided Transformers cards (robot and alt mode) in total but each one is available in two different styles: G1 and Shattered Glass
Grim Monoliths one of the worst of the fast mana offenders and still pretty darn good
