Hey fellow Magic: The Gathering Arena enthusiasts! When it comes to deck-building, I always start by focusing on a specific strategy or theme. Whether you prefer aggro, control, or combo decks, it’s crucial to have a clear game plan in mind. Don’t forget to maintain a good balance between creatures, spells, and lands to ensure consistency in your deck. Lastly, playtest your deck frequently to fine-tune it and make adjustments based on how it performs in different matchups. Happy deck-building!
