Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, remember to focus on a clear strategy. Whether you’re playing aggro, control, or combo, make sure every card in your deck serves a purpose towards your win condition. Don’t forget to fine-tune your mana curve to ensure you have the right balance of early game plays and late-game power. And always playtest your deck to see how it performs against different archetypes. Happy brewing!
