*ding ding!*
SATOSHI: Hello. Let's see the deck.
2 Abra (TR)
2 Kadabra
1 Alakazam (only got one!!)
3 Mewtwo (1 movie promo)
3 Jigglepuff (1 very rare promo 35$!)
2 Wiggletuff
1 Mr. Mime
3 Chansey
3 Tentacool (that's right)

20 Pokemon

3 Pokemon Center
3 Scoop Up
3 Computer Search
4 Plus Power
3 Gust Of Wind
3 Item Finder
1 Prof. Oak

19 Trainers

17 Psychic Energy
SATOSHI: Let's see what we can do.
Since only one of your Mewtwos is a movie promo(I presume you mean the rest
are from the base set), let's take them out. I wouldn't usually do this, but
we'll need the space. With those 3 spaces, add in two more Alakazam(I know
you only have one, but you should try to trade for more). Let's also remove
the Kadabra and Tentacool and put in another Abra. Let's move on.
We have 5 spaces now, so let's first add in three Pokemon Breeders to get
Alakazam into the game fast. With our last two spaces, add in two more
Professor Oak. Regardless of what some people say, card drawing is needed in
stall. Let's move on.
The energy looks good. I suggest dropping one Psychic for another Mr. Mime.
Aside from that, Good job!
