Best. Playmat. Ever. True Power FTW.
Your eyes are not deceiving you. That is a real playmat featuring Ultimate Thor riding a unicorn and calling down the rainbow. It is one of the prizes in the Marvel Super Hero Squad Showdown Championship at Gen Con 2012. Space in the tournament is limited, make sure you sign up early. Get your decks ready and start practicing, that thing is seriously like the best playmat ever.
