Oh...well in that case, I have a plan.
Blademaster, once again I want you to keep using Night Slash on Miru, the closer we can get her to fainting, the better.
But as always, be ready to use Snatch or Magic Coat against any moves prone to having their effects taken away (e.g. Double Team, Imprison) or being reflected back (including Torment and Embargo), and if she goes for Faint Attack, wait for her to hit you, then retaliate by doing a 360 degree Night Slash to catch her by surprise.
Now that I think of it, I just saw that Gothorita can get Imprison through the Japanese Global Link...is that move legal on Gothorita here?
