Hey fellow Planeswalkers! When it comes to building a strong deck in Magic: The Gathering Arena, it’s crucial to pay attention to your card choices. Make sure to have a good balance of card types – including creatures, spells, and artifacts – to ensure versatility in different game situations. Don’t forget to include some powerful synergy between your cards to create devastating combos. And always remember to keep your mana curve in check to ensure you have the right balance of early-game and late-game plays. Happy deck building!
