Hey fellow Planeswalkers! When it comes to building your deck in Magic: The Gathering Arena, always pay attention to your card curve. Make sure you have a good balance of low, mid, and high-cost cards to ensure you have options at every stage of the game. Don’t forget to include some removal spells and card draw to maintain board control and keep your hand full. And most importantly, playtest your deck to see how it performs and make adjustments accordingly. Happy brewing!
