Hi! This is Adam Ruiz here. I was looking at Ness' COTD a few days ago, and I saw that Igglybuff would destroy the deck "Occult Powers" (containing Dark Vileplume, Murkrow, Sneasel.) I do not play this deck, although I think there are a few ways to help this deck if Dark Vileplume is ever Mean Looked in the active position.
1. Grass energy:
Grass energy will activate its good attack, that will possibly kill Murkrow. It can also be used to KO yourself, but hopefully it will kill Murkrow first.
2. Elekid:
If you don't want to waste space for Grass energy, this is a better idea. Just make sure you have a good amount of extra HP left, since it takes a while to KO Murkrow with it.
3. Unown D
This Pokemon prevents all damage by Dark Pokemon by 30, so as long as he/she has less cards in his deck as you, he/she will either be forced to retreat Murkrow, or get decked out. This is the best idea, and will help from Sneasel, too. Just be sure to add 3 or 4 in case 1 of your Unown D's get knocked out. Also, only have one out at a time, because it's power won't work with 2 or more out.
 
If you have one of these decks, it is still playable! Just use one of these tips, or make up your own. Questions? Comments? And please, no hatemail or trash! It would be O.K. if I had another web address, but I don't right now!
