HGSS-on
I am thinking cards like Haunter, Espeon, and other such Spreaders could make this card eat away at your opponents bench while going around their active.
Start it out with Gastly(and soon-to-be Haunter) and get the ball rolling, and when you're done get a free retreat to bring out Mandibuzz(Professor Elm). Say there's a Zekrom out there, DCE'd up and ready to go on the assault. Bummer, we're weak against it. But we can survive at least two regular attacks from him. That's two turns to knock his bench around. Retreat. Bring out Espeon. Spread some chaos around while healing up. Retreat, bring out Haunter(if you haven't Professor Elm'd him out yet, what were you waiting on?). Put a little more pressure on the bench. Haunter took some damage? Its cool. Bring out a fresh Mandibuzz. Take out some more bench'd Pokemon. All the while getting more Haunter, Mandibuzz, or some other Tool on your own bench to back'em up. Throw out some potions when the counters are getting up there.
Whatcha think?
