That's the chance of drawing one specific card from a 40-card deck, with a 6-card starting hand. This is illustrated by the following table:

This is why many duelists stick to a maximum of 40 or 42 cards in their deck. The more cards you have in your deck, the more this probability goes down. In fact, with a 45-card deck, this 15% goes to 13%. In a 50-card deck, this is 12%. 4 turns are worth 1%. Whilst this may not sound like much of an increase, every card counts. Every turn counts.

**Specific Cards in a Hand**

Now let us consider the likelihood of drawing specific cards. If your deck relies on a One-Turn-Kill, how likely is it that the OTK will work?

A Chimeratech OTK consists of:

- Future Fusion (FF)
- Overload Fusion (OF)
- Heavy Storm (HS)

This is assuming we have the cards we need in our deck, extra deck and graveyard, including:

- 2x Chimeratech Overdragon (CO)
- 1+ Cyber Dragon (CD)

Now, the cards we need in our hand (FF, OF, HS) have to be drawn from our deck. In our deck, there are:

- Future Fusion (FF) x2
- Overload Fusion (OF) x3
- Heavy Storm (HS) x1

The chances of drawing these cards from your deck on turn 1 is:

1.07%

See how small that is? That could get even smaller if you introduce more cards into your deck.

The best way to get around these small probabilities is to try to introduce cards that draw more cards in place of other cards that may not otherwise contribute, such as Cardcar D or Cyber Valley in place of Effect Veiler (side Veiler instead).

**Multiple Cards in a Deck**

Having multiples of the same card in a 40-card deck can help immeasurably. Let us illustrate why, with examples.

- 3 of the same card:

Turn 1: 45%

Turn 2: 8.3%

Turn 3: There will only be 33 cards in the deck at the draw phrase of turn 3. Thus, 9.09%.

For the remaining turns, the equation is: (3/cards in deck) * 100

- 2 of the same card:

Turn 1: 33.3%

Turn 2: 5.5%

Turn 3: There will only be 33 cards in the deck at the draw phrase of turn 3. Thus, 6.06%.

For the remaining turns, the equation is: (2/cards in deck) * 100

- 1 of the same card:

Turn 1: 15%

Turn 2: 2.9%

Turn 3: There will only be 33 cards in the deck at the draw phrase of turn 3. Thus, 3.03%.

For the remaining turns, the equation is: (1/cards in deck) * 100

NOW FOR THE IMPORTANT PART.

Look at the numbers:

Do you notice something here? Yes, that's right. The chances of you drawing a specific card from your deck on the third turn TREBLE if you put another of the same card in it. Your challenge is to find out how this affects later turns, and you will soon understand the value of using multiples of the same, necessary card!

3: Turn 3: There will only be 33 cards in the deck at the draw phrase of turn 3. Thus,9.09%.

2: Turn 3: There will only be 33 cards in the deck at the draw phrase of turn 3. Thus,6.06%.

1: Turn 3: There will only be 33 cards in the deck at the draw phrase of turn 3. Thus,3.03%.

However, be cautious. There are some cards you don't want to have clogging up your hand, like Future Fusion when you already have a Chimeratech on the field, for example. In this case, it would be wise to minimise the probability of you drawing such cards. Something I found on the internet that was quite useful was a Deck Builder Toolkit. Have a look. It helps you to work out the likelihood of drawing a specific hand, and you could also use it to work out the drawing of a specific card if you're having trouble with your maths.

To summarise, probability is important to consider when working out what cards should go in your deck and how many. The extra cards you don't put in (as they may become a dead draw if drawn at the wrong time) could be replaced with even more helpful cards, thus making the difference between victory, defeat and whether a deck has been built smartly. Defining probability is often a subconscious thing for many of us, and is what divides the pros from the experts in tournaments.

Happy deck building!
