I'm not sure how I feel about that art, but everything else about this card is absolutely perfect.
In regards to furball's cost analysis, I would suggest that because creatures dealing spell damage is part of aether's thing currently (psion and shard of wisdom) that having it cost 1 more than it probably would in aether is perfectly fine, much like how mirror/reflective shield is so much cheaper than emerald shield/jade shield, even factoring in the +1 DR.
