Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, one tip I swear by is to always have a clear game plan in mind. Whether you’re going for an aggro, control, or combo deck, make sure every card you include serves a purpose towards achieving that strategy. Don’t forget to pay attention to your mana curve to ensure you have a good balance of early game plays and late-game threats. And most importantly, playtest your deck against different archetypes to fine-tune it for the best performance on the ladder. May your opening hands be blessed with perfect mana!
