Well our ace in the hole right now is Black's Zangoose. It knows Fury Cutter and it just shreds Dark, Grass and Psychic(a Typing prevalent on nearly all of the Pokemon down there, including Nuzleaf). The critical Pokemon that we have to KO is Pancham because Fighting is a Normal type's worst nightmare. Caite is thundershocking the Pancham and I advocate Hit moving down to Wing Attack it. Granted it still might survive that, hence why I want Priscilla to Growl on M3 so as to weaken the power of the enemy's first moves down there. No idea if Black can OHKO that Sneasel but if past history is any indication, it's a no since it's in Tall Grass. However, so is Black so it's not the end of the world. With Glacier advocated to sprint east, he can then move down and use an Ice move on Nuzleaf or the Bug Type down there. Salandit might hit him with an Ember though and right now Rinnia is the only viable counter.
