I ran it with cacturne d for awhile, along with pelipper d. I'd put cessation on crobat, retreat, send up cacturne, use power, pelipper it back, put back up crobat, and radar jam/snipe. If you don't want to play cessation crystal, you can play crobat ex, too - 2 pelipper in play will allow you to pull back crobat d, send up crobat ex, place a counter, retreat, bring up cacturne, place a counter, pull back, and snipe anything for 80.
But then I realized that mewtric does the same darn thing much quicker and cheaper, so I put crobat d back in my binder.
