Hey fellow Planeswalkers! When it comes to building a killer deck in Magic: The Gathering Arena, it’s all about finding the right balance of cards. Make sure to include a good mix of creatures, spells, and lands to ensure you have options in any situation. Don’t forget about those powerful rare and mythic rare cards that can really turn the tide of a game. And always keep an eye on your mana curve to make sure you can cast your spells when you need them. Happy brewing!
