Pokémon TCG Card Lists

Blizzzard's Strategy
Best Pokémon of each Set
Base 1:Charizard (Pokémon power is good because it can burn a double colorless to recharge quickly)
Jungle: Clefable (Metronome can work wonders)
Fossil: Ditto (Transform.  Need I say more?)
Team Rocket: Dark Muk (increases retreat cost for your opponent.  If it's a Snorlax or someone like it as your opponent's pokemon, retreat is impossible for a while.)
Gym Heroes: Lt. Surge's Electabuzz (With a Few Nightly Garbage Run cards in your deck, you become an electrical blowout.)
Gym Challenge: Sabrina's Kadabra (Life Drain, if it works, can drain your opponent down to 10 hp.  That is a very good ally and can render one potion useless because of the 30 Damage from Psyshot)
Neo Genesis: Onyx (I know what you are thinking.  Why Onyx?  With rage and screech, you can do more damage to the defending Pokémon)
Neo Discovery: Metapod (hey, 2 Grass energy to heal it and evolve it at the same time.  Not a bad ally to get out a Butterfree quick

Best Trainers of Each Set

Base 1: Bill (2 cards.  No questions asked.)
Jungle: Pokeball (not much surprise there.  It's the ONLY trainer.  But, pulling out a Pokémon can't be that bad.)
Fossil: Energy Search (get out the energy card you need without flipping a coin.)
Team Rocket: Nightly Garbage Run (hey, taking out 3 cards from your discard pile to your hand can come in handy)
Gym Heroes/Challenge: Master Ball (hey, pull out a Pokémon.  No questions asked. 
Neo Genesis: Double Gust (ignore retreat costs)
Neo Discovery: Energy Arc (can pull out energy)

Digmon's Strategy
Best Pokémon of Each Set
Base 1: *tie*Charizard(Energy Burn+Double Colorless) and Nidoking(Toxic)
Jungle: *tie*Clefable(Metronome)and Venomoth(Poison and Confusion in one attack)
Fossil: Moltres(its attack discards energies and makes your opponent discard an equal number of cards from the top of the deck,making him closer to a loss via deck exhaustion)
Team Rocket: Dark Muk(same reason as what's there + making it harder for a powerful AND poisoned/confused pokemon to retreat can put one less strong pokemon in your way,making it good to use Venomoth followed by Dark Muk)
Gym Heroes: Misty's Tentacruel(most of the strongest pokemon are Fire-types which would have a disadvantage against it,and its Pokemon Power lets it retreat)
Gym Challenge: Blaine's Arcainine(its strongest attack does 120 damage which is a 1-hit kill)
Neo Discovery: Quilava(the status effect Char,done by one of its attacks,does damage equal to the poison from Nidoking's Toxic)

Best Trainers of Each Set
Base 1: *tie*Pokémon Center(healing,will mention a way to not discard energies later)/Full Heal(BIG DUH!)/Computer Search(pull any Pokémon or Trainer from your deck)/Super Energy Removal(just the thing to stop a Charizard or Blaine's Arcainine)
Team Rocket: Nightly Garbage Run(Same reason+with 2 you can use one to pull out the other along with 2 more cards)
Gym Heroes: Energy Flow(put energies back into your hand then use Pokemon Center to heal)
Gym Challenge: Max Revive(DUH!)
Neo Genesis: Professor Elm(if your deck is close to running out,you can use the 2 Nightly Garbage Runs and shuffle the cards into your deck).
