How to improve a theme deck

[Timber]

I got the heart gold soul silver mind flood theme deck and so I could play at the local club with my son, only I found that I lost bad and the deck needs improvement, these are the only cards I have (my son has many) What is the best simple way to expand?

With that deck, it would be good to abuse Slowbro's Madkinesis. It can do 90 damage for 3 .
Keep Professor Elm's Training Method and Professor Oak's New Theory. Those seem pretty useful.

A simple way would be buying boosters or singles. I hear Stormfront has good cards. A normal runs about 2 basic, 2 stage 1, and 2 stage 2. Putting more would be alright.

From what I've seen on these forums, supporters and having a card that lets you continually draw is common. Good supporters would be Bebe's Search, Roseanne's Research, Pokemon Collector, and Luxury Ball. Also, Interviewer's Questions and an Engineer's Adjustments are good for starting out.

The best way? Buy single boosters, booster boxes, or trade for the cards you need.

If you're new to the hobby, (like I was nine months ago) you'll see/hear/read terms like 'consistency' and 'draw power'. You'll hear other terms of course, but I tend to lean on these two when building a deck.

Speed kills in this game, and the faster you can set up, the quicker you'll be able to exert your will over your opponent. Look for cards that help you cruise through your deck. Uxie is a great card as, when played from your hand to the bench, it's poke-power 'set-up' allows you to draw cards until you have seven in your hand. Uxie was a free card during league play this last year, and may still be available at your local club. Ask the league leader for info.

All the cards CV mentioned will help improve consistency and add draw power to your deck. If you mean to play in tournaments this fall, be aware of which cards/sets are in format, and give each a thorough look before you commit to buying.

Good Luck

It comes with 13× Water Energy & 11× Psychic Energy should I replace 4 energy with supporters? What should I cut out to make room for supporters or stage 1s?
1× Feraligatr
2× Croconaw
4× Totodile
1× Exeggutor
4× Exeggcute
1× Hypno
4× Drowzee
2× Slowbro
4× Slowpoke
2× Jynx
2× Bill
1× Full Heal
2× Poké Ball
2× Professor Elm's Training Method
2× Professor Oak's New Theory
2× Moomoo Milk

[Clearea Vystein]

Both Jynx, 2 Slowpokes, 3 Drowzees, 2 Exeggcute, 1 Totodile. (-10)

The only water Pokemon is Feraligatr, so I don't think you'll need that much Water Energy. Keep it between 8 and 10. The Pyschic Energy seems fine enough.

This would leave you with:

14 Pokemon
19 to 21 Energy
11 Trainers

and 10 extra spaces.

We have an entire contest geared toward doing just this (theme deck enhancement for new young players)

"I Play Theme Decks" is a good thread to follow when it begins after worlds (link is in my signature)

The quickest way to modify a theme deck is to take out the extraneous Pokemon and focus the pokemon lines so you have more copies of the main evolution line. Then you strengthen the trainer/supporter count.

Keep in mind (THIS IS VERY IMPORTANT):
You have shown up to a tournament-training league with a "for fun" deck.

The people you are playing against have decks that were built from scratch and are designed to be VERY strong.

Theme Deck play is FUN because you have very little control over how your cards will play out.

ENJOY the randomness of your theme decks with your kid and avoid tournament playtesting for awhile. Kick it up a notch a few cards at a time.

I really wish I hadn't thrown my kid/family into tournament play while they were REALLY enjoying passing around theme decks and trying to see who can win "this time."

Tournament play is INTENSE. If your kid has fun w/ INTENSE, then, by all means, jump right in...

Thank you for your advice, I think I was already to old by the time pokemon came out and as a 30 year old haven't traveled in any circles with pokemon players. My son and his friends have been colecting them for a while now, but none of them really knew how to play and that kind of thing bugs me, so now I'll be the dad who will be taking them to the local leauge. Having taken my son I was surprised at the complexity and fun ( so much for my stereotype ).

Yet my theme deck was put to shame when I played at League and although my son has a few hundred pokemon he had already traded many of his duplicates and +, which makes it hard to form a deck. I just feel sorry for a few of his friends who had traded away all their energies away.

Buy another of the same theme deck, and combine the two, and take out a bunch of energies.

When I started playing, I got two SV Ignition theme decks and made a Masquerain/Venusaur deck from it - a deck which a variation of I'm running now.

^ This is very true. Also, there are Tins you can buy that will score you Feraligatr Prime, a very handy Pokemon! Buying 2 of these is a very good idea, considering they come with 4 packs as well! Hope I helped! :)
