This might be one of the premier threats in DMU limited. Quite bad against red removal, but the ability to sort of give all your creatures flying (in that they pump all their power into this) might be huge. Will need to see if the removal stacks up or if there are enough reach or 2-power flyers to hold it in check.
Looks boring? Yes. Going to get you out of nowhere in Limited? Also yes.
