Make sure you have a good mix of creatures, spells, and lands to ensure consistency in your draws. Pay attention to your mana curve to make sure you can play your cards when you need them. And don’t forget about synergy – building a deck around a specific theme or strategy can really take your game to the next level. Happy brewing!
