Hello welcome to calculating card draw. There are two thing I want to say.. first, dont forget auto draw takes away from the amount of cards you have in your opening hand. Second, dont forget auto draw takes away from the chances of drawing any time during a game where you will automatically auto draw.

== Chances of Drawing a Card After Opening Hand ==

This is pretty easy and its a good place to start because the math is so simple. This section will assume that you arent auto drawing the turn your calculating the odds of card draw. Because if theres a card you want and your going to auto draw your chances are zero.

You also have to take into consideration any base buildings you have auto drawn that werent in your deck. For instance your playing a mono MF deck with 40 cards and you originaly put 1 Dwarven Hall in it. That hall gets destroyed so the game graciously auto draws another Dwarven Hall for you. Now that 40 card deck has become a 41 card deck.

The math is really simple .Its assuming you have added your own base buildings. If you didnt, you need to add for the building. I'll go over calculating after auto drawn building that werent in the deck second. It also assumes you havnt mulliganed.

LEGEND:

X = The round it is
Outs = The amount of cards "LEFT" in your deck that youd like to draw
(the 7 is taking into consideration the first cards you have already draw. The number 7 in the
equation will have to be changed to the amount of cards you have mulliganed down to.

EQUATION:

(Outs)/(Total deck size - (7+X)

SAMPLE SCENARIO: (Pay close attention to the quotes if you did not understand the equation above) You "did not mulligan." Its turn "16" , going on 17 and you either need an ascent or an entangle or your going to lose for sure. Your deck starting out was "43" cards. In the 43 card deck was "2 ascents" and "3 entangles". You added your own base buildings so you "did not auto draw any cards." You have already "played 1 asccent and 2 entangles." What are the odds of getting either one that you so direly need.

1 ascent left, 1 entangle left = 2 outs.

(2)/(43-(7+16)= 2/20.

So 2 divided by 20 is .10. So since its .10 that means you have a 10% chance of drawing a card that you need in this case. Now keep in mind .10 is the same as .1 or .100 or even .100000000. Thats the way decimals work.

CRASH COURSE IN CALCULATING WHEN YOU HAVE AUTO DRAWN OR MULLIGANED:

LEGEND:

X = The round it is
Y = The number of base buildings you have auto drawn (adding to deck size)
Z = The number of cards you have mulliganed down to
Outs = The amount of cards "LEFT" in your deck that youd like to draw

EQUATION:

(Outs)/(Total deck size + Y) - (Z+X)
