The straight MUK ex beatdown decks posted so far are weak to psychic. This week @ the shack I faced 4 psychic decks (one was a grumpig/amphy deck) and lost to 3. Kecleon and Wobby were not enough to win for me against psychic although I did take down a gardy ex with kecleon. I have decided to try playing Muk EX like the old dark muk decks and add dark pokemon to cover my psy weakness. Here's my new list Note-Umbreon list is lower in the post Pokemon: 17 4 Grimer 4 Muk ex 2 absol 2 murkrow 3 Roselia - I like this card but do not use it that often 2 zangoose - may switch out one for a tech seviper Trainers: 25 4 Oak's Research 4 shaman 2 birch 2 fan club 2 TV 3 potion 2 Fast Ball 2 masterball 2 poke nav - may drop for another masterball and potion 2 Low Pressure System Energy: 18 13 Grass 4 dark 1 multi I find with this deck the trick is to get a muk ex active by turn 2 or 3. You typically loose the first one which is fine. Then I use another muk or an absol. Absol is great for late comebacks. Even so, I find that you really need to focus on keeping a muk ex active as much as possible. Support pokes are use situationally. This list is basically a fast swarm deck which shuts off powers.
