I threw Curse on my Banette. Tried unsuccessfully a few times to wisp it (burns were removed in the full restores), but was able to stall with a little luck and a lot of Detect juggling on Tranquill. Definitely a challenge, but a fun one. In the end, he died to the last tick of Curse, after three full restores, with only my half-health Banette still alive. Close call.
