Does anyone know of any software for calculating the odds. Sure Excel or other spreadsheet software would do it, if you know how to set up the formula correctly. I am looking for example at determining the chance of drawing a third mana, by turn three, if I started with 2 mana in hand and there are 22 mana in the deck. Then to be able to compare this to what would happen if I put 24 mana or 20 mana in the deck.
I used to do this myself by setting up spreadsheets in Excel, but I am struggling to repeat this. Any pointers appreciated.
