so, couple of questions...

i'm making a furfrou with this set because i saw it and took a shining to it:

snarl
charge beam
cotton guard
rest

w/ maranga berry

so i have a few questions:

what nature would be ideal for furfrou?
how should i EV train it?
does a trim do anything worth while to furfrou?
how do i get a maranga berry?
is there any other recovery besides rest?
