I collect and play mainly with team rocket cards, and after playing MANY games with them I think I could offer some help with strategies involving mainly team rocket cards.
   
   My first observation is fairly obvious and involves decks that tire themselves out quickly. Nightly garbage run(descriptions of cards @ bottom) is a great way to prevent this little annoyance.

   Secondly, for those of you running decks that rely on basic pokemon on the bench quickly,            then a combination of challenge, and Dark Dragonite works wonders for decks like that.

   Next I would like to speak to all of you out there running combo decks, which I usually don't do for energy reasons. Rainbow energy is a good card although overrated, it works great on pokemon such as psyduck,(base and rocket) and exeggcute which have attacks that use either grass or psychic energy.  When I do use combo energy decks, I would rather use energy search
for lots of reasons, it is much easier to find (common) and it doesn't  do ten damage to the pokemon that you attach it to!

   Finally, I wanted to inform you about a killer combination of fighting/grass pokemon that will kill just about any deck, Dark Muk's pokemon power (opponent pays two more colorless energy to retreat) and Dark Dugtrio's pokemon power (if opponent retreats flip a coin, if heads do twenty damage to that pokemon) will make it close to impossible for your opponent to retreat his/her active pokemon

   Nightly Garbage run (trainer)
   
   choose up to three basic pokemon,
   evolution cards, and or basic energy
   cards from your discard pile, show them
   to your opponent and shuffle them into
   your deck.

   Challenge (trainer)
   
   if opponent accepts, each of you search
   decks for any number of basic pokemon
   cards and puts them on your benches,
   if opponent declines or benches are full,
   draw two cards.

   Dark Dragonite  Evolves from Dark Dragonair

   70HP  resistance:fighting-30  
   retreat cost: two colorless energy
   pokemon power: summon minions
   when you play Dark Dragonite from
   your hand, search your deck for up to
   two basic pokemon and put them on
   your bench.  Shuffle deck afterward.

   CCCC: 70HP  Dragon tail-flip a coin. if tails,
   this attack does nothing.

   Dark Muk  Evolves from Grimer
   
   60HP weakness: psychic  
   retreat cost: two colorless energy
   pokemon power: sticky goo
   (described above)
   GG: 20HP sludge punch-the defending
   pokemon is now poisoned
   
   Dark Dugtrio Evolves from Diglett
   50HP weakness: grass
   resistance: electric
   retreat cost: two colorless energy
   pokemon power: sinkhole
   (described above)
   FF: 20+ Knock Down-opponent
   flips coin if tails, attack does 20+
   20 more. If heads attack does
   20 damage
