Optional deck size of Magic the Gathering
As a Magic the Gathering player, you’ve undoubtedly wondered how many cards you should play with in your deck. You’ve probably questioned if you should stick to the minimum standard of 60 cards or would it be better to throw in a few more crucial cards to the game and go up to 65, 70 or more cards in your deck.
while it may be tempting to cram in as many cards as you can into your deck, the general consensus among pro players is to keep it as close to 60 cards as possible. In fact, 60 cards in a deck is really the most optimal strategy for the game.
It really breaks down to simple math. The more you go past 60 cards, the less chance you’ll have to draw a paticular card from your deck. That’s because Magic the Gathering restrict you to only including four copie of any one nonbasic land card. The future you go past 60 cards, the less chance you have of seeing a certain card.
Here’s a more through explanation. Imagine you are playing with four Dispels, an instant allows you to counter a target spell.
In a 60 card deck, Dispel would be one out of every 15 card (60/4=15). In a 70 card deck, Dispel would be one out of every 18 cards ( 70/4=17.5). In an 80 card deck, Dispel would be one out of every 20 cards (80/4=20). In a 100 card deck, Dispel would be one out of every 25 cards (100/4=25).
As you can see the more cards you put into your deck the less chance you have of pulling that card. In a 60 card deck, you have the best odds of pulling Dispel before the game ends. However, it’s not guaranteed that you will pull that card, but your chance of drawing it are a lot better than if you cram in 100 cards.
When constructing your deck try as hard as you can to keep it to 60 cards. If you have to go to 61 or 62 it’s not the end of the world. But remember, those one or two extra cards may reduce your chance of drawing a crucial card you need to win the game. So make sure that they really count.
