Hey fellow Planeswalkers! When building a deck in Magic: The Gathering Arena, remember to focus on synergy between your cards. Whether you’re going for an aggro, control, or combo deck, make sure your cards work well together to maximize their potential. Don’t forget to include a good balance of creatures, spells, and lands to ensure consistency in your draws. And always playtest your deck to fine-tune it based on how it performs in actual matches. Good luck, and may your opening hand always be full of gas!
