Hey a person once told me that dark arbok and dark golbat was a good combo.  You can totally destroy the bench and the active.  But there is one problem however - Dark Golbat is extremely weak.  his HP is too little for a stage 1 and his pokemon power is weak(only 10 dam.?) and he only does 20.  frankly I think hitmonlee is better.  he is a basic, has 10 more HP, and can do 50 to the active and 20 to the bench, unlike golbat's 20 to the active and 20 to the bench.  With this combo(hitmonlee+arbok) the opponents bench will totally be destroyed!  however low hit points is a major problem so include defenders.  here is an example deck.
 
4 Rocket Ekans
3 DarkArbok
4 Hitmonlee
4 Lickitung
 
2 Bill
3 Oak
2 Switch
2 GOW
2 CPU Search
2 Itemfinder
2 ER
2 SER
3 Defender
2 Energy Retrieval
 
10 G energy
10 F Energy
3 Rainbow energy
 
Great huh?  the lickitunges are in there because of the deck's major weakness to psychic.  The rainbow energies are there because all the pokemon require colored energy to attack but watch out - it does 10 points of damage and the pokemon have low hp.  have fun with the deck.  k?  peace out.
