Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, remember to focus on a cohesive strategy. Whether you prefer aggro, control, or combo decks, make sure every card choice aligns with your game plan. Pay attention to your mana curve to ensure you have a balanced mix of early game plays and late-game bombs. Don’t forget to include removal and card draw to maintain board presence and hand advantage. And most importantly, playtest your deck against different archetypes to fine-tune it for the best results. Happy brewing!
