Okay..this is my first writing to the almighty Pojo site...I will talk about
the Dk Arbok and Dk Golbat combo

Dk Arbok

HP: 60
weak:psychic
moves: GG
    ten to any pokemon, that pokemon cant use its powers
        GGG
    ten to all pokemon on the bench, active pokemon poisoned

Dk Golbat

HP:50
weak:psychic
res: fighting
pokemon power:
    when he comes into play, ten to any pokemon
moves: GG
    20 damage to any pokemon

Combo:
    This combo is basically used to attack the bench. Arbok can be used to
hurt every body on the bench while the Golbat uses his pokemon power to add a
little more damage. Once Arbok is killed, Golbat can finish off the job. This
combo has flexibility, such as using the Challenge to try and trick the
opponent to fill up the bench for you to destroy.  You could also gust of
wind a pokemon that has alot of retreat cost that could do you no harm
(Snorlax) while you pick off the bench.  I currently use this combo in one of
my 6 decks along with a Dk Machoke because he can pull someone from the bench
and do 20 to them or push the defending pokemon back while hurting them 30.
This works out pretty well.
    The greatest weakness that I can see is that they are all weak to
psychic, but a couple of colorless creatures can help with that.

It has been an honor writing this. I hope to write more articles in the
future. For anyone who wants to talk about combos or strategies about the
pokemon TCG, you can contact me at GE64007@aol.com
