Mimeo, Taunt Willow until you're successful, then blast him with as many Signal Beams as you can, hopefully you can shake off the paralysis sooner or later.

Sub:

If Willow comes close to you for a physical attack after he's taunted, you should have a better shot with Signal Beam, so in that kind of case, fire it toward his face if he comes too close for comfort.

Incase he manages to get in a Double Team despite your taunting (no matter how many attempts you make at taunting him), Swift away the clones.
