Whimsicott is one of the best users of Assault Vest in RU. Thanks to its unique Grass / Fairy typing, good bulk, great Speed, strong STAB moves, one of which provides recovery, and the ever-handy U-turn, Assault Vest Whimsicott makes for a good pivot that can keep itself healthy, check top threats, and maintain momentum. It also counters one of RU's possible new drops, Kingdra, as it can even take the most common coverage move on Kingdra, Hidden Power Poison, thanks to Assault Vest:
252+ SpA Kingdra Hidden Power Poison vs. 4 HP / 0 SpD Assault Vest Whimsicott: 200-236 (76.3 - 90%) -- guaranteed 2HKO
Overall, Assault Vest Whimsicott is a great, underrated set that should really be seeing more usage than it does currently.
