Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, it’s all about finding the right balance. Make sure your deck has a good mix of creatures, spells, and lands to ensure consistency. Don’t forget to include some removal spells and card draw to handle different situations. Also, pay attention to your mana curve to make sure you have the right amount of low-cost and high-cost cards. And most importantly, playtest your deck regularly to see how it performs and make adjustments accordingly. Happy brewing!
