Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, remember to focus on consistency. Stick to the 60-card minimum to ensure you draw your best cards more often. Also, include a good mix of creatures, spells, and lands to cover all your bases. Don’t forget to have a game plan – whether it’s aggro, control, or combo, make sure your cards work towards that goal. And lastly, playtest your deck to see how it performs and make adjustments accordingly. Good luck and may your opening hand always be perfect!
