While many pro players are advocates for the 9 card strategy, some players prefer to have a little bit more variety in their deck. Another strategy that you can tiy to deploy is to create a deck around 12 different cards. When building a deck around 12 different cards you would include three copies of each. 12 different cards x 3 each = 36. 36 + 24 = 60 cards in a deck. This approach can lend itself to a wider assortment of spells, but at the cost of having a lesser chance of pulling one particular card. Instead of having a 1 in 15 chance of pulling a card (using the 9 card strategy) you reduce your odds to 1 in 20. Some players are o.k. with this decision, while others are not. Its up to you to experiment with which strategy works best for you. Add让ionallv, you could also try to incorporate a hybrid strategy if you want to play a few extra high costing mana cards. Let s say there are one or two high cost mana cards that you cannot live without and for whatever reason you must include them in your deck. You could bend the rules a little regarding the 9 card strategy by doing something such as this: 8 cards with 4 copies each 2 cards with 2 copies each (the high cost mana cards) Or 7 cards with 4 copies each 3 cards with 3 copies each (the high cost mana cards) 1 card with 2 copies (preferably low to medium costing cards to adhere to the mana curve rule) Regardless of the strategy you choose, it's best that you test it out multiple times before attempting to adjust it. For example, if you choose to use the 12 card strategy, we suggest you play at least 20-30 different games with it so you can determine if you're pulling enough of the right cards. If not, it might be best to move to the 9 card strategy or a hybrid approach. Please send email to [email protected] if you have any questions.
