How can you make a magic deck stronger?

Answer 1

One method is to pick a specific effect or style and only choose cards that focus on that effect or style. Focusing your deck in this manner improves your chances of drawing a card useful to your strategy. For example, in a deck based on spells that do direct damage (a Burn deck), incorporating spells with other effects such as healing you or forcing an opponent to discard (while not bad spells in and of themselves) water down your goals. Another way would be to make sure your mana curve is reasonable. Too many expensive spells make it more likely that you will have cards in your hand that you can't cast. If you are finding you don't have enough mana during play, consider adding more land cards, or replacing mana heavy spells with more cost efficient cards. The opposite is true if you constantly have too Much mana and not enough creatures or spells (referred to as Flooding) remove some lands or add more creatures/spells. Hope this helps!
