Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, my biggest tip is to focus on synergy. Make sure your cards work well together and have a clear win condition. Don’t forget to balance your mana curve to have a good mix of low-cost and high-cost spells. And always playtest your deck to see how it performs against different strategies. Happy brewing! #MTGArena #DeckBuildingTips 🧙‍♂️✨
