Very nice. So a minor to make it move somewhere, then a standard to attack, and maybe an OA to have it do and OA. Overall pretty nice, and looks like it could be powerful. If nothing else, you can have it stand somewhere, blocking a square and get a 2:1 deal on a haling surge, meaning it will have double your HS value in hit points and you lose one if it is killed.
It looks like summoning will be very interesting tactically.
