Card of the Day - Goromak

This is an old design.  I wanted to make a powerful blue flier that was absurdly cheap.  It was basically as mashup of Tar Pit Warrior and Serendib Efreet.  Now that Phantasmal Dragon exists, I feel that this could possibly be pushed a bit further. 6/7 perhaps? 6/8?

 Edit:  Cleaned up templating a bit and made it 6/7.
