"The one thing you're forgetting-that Nidoran seems like it'll faint in a faint breeze. (also, shouldn't Budew be at -1, due to drop decay from Leaf Storm?)
Float-you're most likely going to survive that first bomb, so intercept that Toxic attack from Budew- then Ice Beam Budew repeatedly!yay magic guard
Flare-take no chances. Play things safe with an Ember against Nidoran-that ought to finish it off, if it doesn't the Hail will-then Flame Charge straight at Budew twice!"
