Hey fellow Planeswalkers! When building your deck in Magic: The Gathering Arena, always start with a clear strategy in mind. Whether you prefer aggro, control, or combo decks, make sure every card you include serves a purpose towards achieving your win condition. Don’t forget to keep your mana curve in check to ensure you have a good balance of early game plays and late-game power. And most importantly, playtest your deck regularly to fine-tune it based on your matchups. Happy brewing!
