💬 Quick Tips
Prize check
If a copy is prized, subtract it before trusting the odds. One prized key card can change your setup window more than an extra draw card does.
Search check
Search effects are strongest when they increase the number of cards you actually inspect, not just the number of cards you keep in hand.
This calculator uses a clean planning approximation: it treats search cards as extra cards you look at, then estimates the chance to hit at least one or two copies inside your chosen turn window.
The probability and mathematics behind Pokemon TCG deck determine the success of those decks. Understanding the mathematics behind Pokemon TCG allow for a person to build a more successful deck. When a person finds themself without any of the necessary Pokemon in there opening hand, it is due to the mathematics of their deck having to few of the specific cards.
If there are too few of the necessary cards in a persons deck, there will be a low probability of drawing those cards, which will lead to a loss in the game. A person must consider the requirements for a given Pokemon TCG deck. Most deck require certain numbers of Basic Pokemon, evolution cards, and Rare Candy cards to play their Stage 2 Pokemon line.
Simple Math to Build a Better Pokemon TCG Deck
If a person creates a deck that contains only one copy of a necessary card, the chance of drawing that card is going to be low. By increasing the number of copies of that necessary card that the player includes in the deck, the chance of drawing that card increase. Thus, increasing the number of copies of any card increases the probability that a person will find that specific card within their early turns in the game.
Another factor to consider within the mathematics of a Pokemon TCG deck are the prize cards. Prize cards are removed from the deck once they are played in a persons game. Therefore, if a persons deck contain any of the necessary cards within the prize cards, then the player cannot draw those cards.
To calculate the number of necessary cards within the deck, the player should subtract the number of those cards within the prize cards from the total number of necessary cards. By decreasing the number of necessary cards within the deck, the probability of searching for those specific cards within the deck also decrease. Therefore, the player must account for the presence of prize cards when calculating the odds of success with a given deck.
Another factor within the mathematics of a Pokemon TCG deck are search effects, such as Ultra Ball and Nest Ball. Search effects allow a player to search their deck for specific cards. By increasing the number of cards that a player sees within their deck, the probability of finding a specific card increase.
Thus, players must decide the apropriate time to use these search effects. Using search effects early in the game will allow a player to have more speedier in their game. Yet, using these effects later in the game may be necessary if the prize cards contain necessary game pieces.
The total number of cards that a player will see during the game is calculated by early draws, search effects, and opening hands. The total number of cards seen will determine the reliability of a players deck. Another factor within the mathematics of a Pokemon TCG deck is the size of the deck.
A players deck contains sixty cards. If many different type of cards are added to sixty card deck, the probability of drawing any specific card from that deck decreases. Thus, as the probability of drawing a players necessary cards decrease, their consistency and reliability with drawing those cards also decrease.
By decreasing the total number of cards within a deck, a player can increase the probability of drawing there necessary cards. A person can use a few different mathematical formulas to assess the effectiveness of their deck. One formula is calculating the probability of drawing a number of “hits” out of a number of cards within a deck using hypergeometric distribution.
Additionally, calculating the expected value will allow a person to determine the average number of copies of their necessary card that they will draw into their deck. Finally, calculating the miss rate will allow a person to determine how often they will not be able to draw these necessary cards into their deck. If the miss rate is too high for a players deck, then the player can increase the number of copies of the necessary card or decrease the total size of the deck to increase the chance of drawing the necessary card.
Overall, the main goal with building a Pokemon TCG deck is to have consistency in drawing the necessary cards. Thus, players should utilize search effects to increase the total number of cards within the deck, and increase the number of copies of the necessary cards within the deck. While the mathematics of Pokemon TCG will not ensure that a player wins every game that they play, using the mathematics to build there deck ensures that they will have the most consistant and reliable deck possible.
