Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, I always start by focusing on a clear strategy. Whether you prefer aggro, control, or combo decks, knowing your win condition is key. Don’t forget to maintain a good balance between spells, creatures, and lands to ensure consistency. And always playtest your deck to see how it performs against different archetypes. Remember, refining your deck is a continuous process, so don’t be afraid to make changes based on your play experience. Keep shuffling those cards and may your opening hand always be favorable!
