Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, always remember to have a clear strategy in mind. Whether you’re going for an aggressive aggro deck or a control-focused one, make sure your card choices align with your game plan. Don’t forget to keep an eye on your mana curve to ensure you have a good balance of early game plays and late-game power. And most importantly, playtest your deck to see how it performs and make adjustments accordingly. Happy brewing!
