Ha ha ha... I'm wondering on that, too. It's frail, but with the ability to trapping somebody else nearly indiscriminately (you'll need to be part flying or levitating to avoid it from the start of his appearance), I suspect he'll go suspect pretty soon, for I worry he'll cause an over-centralization around the UU metagame, just like Garchomp was in OU, and banished to BL.
