Statistical Analysis PTCG II - Successful Evolutions
William Hung
April 19, 2003

Dear trainers,
Hello, I hope you all had a chance to read through the first installment of my articles.  I will use my first article as reference as appropriate.  Keep in mind all these material is meant to help prepare for Skyridge SBZ, thus it is Modified.

I will based all my calculations based on Deckulator, and it can be found at www.implair.com/deckulator/deckulator.html.
 
From the analysis of card-drawing engine, I will now claim that we can draw at LEAST 14 cards into the deck by turn 3.  Your deck's success is obviously get everything out by turn X, where turn X is when your opponent draws a card or card(s) that says "I win, you lose."  Although there is no single overpowered
card in Modified, a deck like Gatr (Downpour) and Parasect is close to it.  It is next to impossible to beat this deck if you're not ready with your main-line evolution.  Keep in mind shuffling and drawing 7 cards is not the
same as drawing 7 cards into the deck.

Quick reference example: You have 4 cards in your hand.  You play Elm to shuffle to draw 7 cards.  The number of cards drawn into the deck equal 7-4=3. Thus, with an initial 8-card hand, it is 11 cards drawn into the deck.

Now, let's go through Evolution ratios quickly.  If we based this decision purely on statistics, we'll quickly conclude 4-4-4 for a Stage 2.  4-4 for Stage 1.  You get the picture.  However, this isn't optimal.  Depending on the deck, this is bad "card economy".  Having Stage 2 as dead cards is very bad in Modified.  "Card economy" will be the last (upcoming) installment of these articles.

I will use Aquapolis Jumpluff as a deck-building example.  It is by no means stronger than Gatrs, Blastoise, but you will get a very good idea of how things work (Assume 14 cards drawn by turn 3).

Need:
1 of 4 Hoppip
1 of 4 Skiploom
1 of 3 Jumpluff
1 of 16 Grass Energy (for simplicity)

With two Pokemon Traders, your success is 33.6%
With three Pokemon Traders, it is 38%.
With four Pokemon Traders, it is 40.8%

So, put either two or three Pokemon Trader into your deck.

Once you add two more Pokemon Fan Club, assuming two Pokemon Trader, then the success rate is 43.2%.

What does this all mean?  This means we want a secondary attacker, because it allows us to put pressure on the opponent much earlier.  Thus, Kingdra and Steelix together is more successful than Kingdra itself because you have two ways out.

Please note from the first article the probability of having a crucial draw card early game.  4 Elm, 4 Copycat, 3 Cleffa yields 83% rate of having at least one of each by turn 3, assuming you're not having them in your initial hand.  (0.432)(0.83) = 0.36 = 36%.

So the success rate for 4-4-3 Stage 2 evolution, 14 cards drawn into the deck is 36%.  The actual success rate is slightly higher, but not too far off. Thus, Stage 2 evolutions must be incredible game winners, while Stage 1 can be "optimal" Pokemon, such as Steelix.  In general, Stage 1 can be used to pressure the opponent early, as well as giving you time to get Stage 2 out.

There are certainly exceptions, notably Entei/Magcargo.  Now that we established solid ground for successful evolution, the last installment will use comparison and statistics to discuss "card economy".  It is the heart of these three articles, going into Modified metagame and match-ups.  Please stay tuned.

Sincerely,
William Hung
