Many Pokemon are, for lack of a better word, useless. Whether it's Bibarel, Noctowl, or Illumise, there's simply no reason why they should be used over others.
So, let's brighten these sad creature's days by giving them just ONE ability that would make them competitively viable. If that's even possible, that is; some are irredeemable. But the least you could do is try.
Here's the rules:
1. You must give assign an Ability to the Pokemon the above person selected to make that Pokemon competitively viable. You then post your own Pokemon you want upgraded.
2. The following Abilities are not allowed: Wonder Guard, Moody, Speed Boost, Drizzle, Drought, Sand Stream, Snow Warning.
There's probably other overpowered abilities that'd extreme-buff any 'mon, but I forgot it. Just use your judgement.
