Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, it’s all about finding the right balance. Make sure you have a good mix of creatures, spells, and lands to ensure consistency in your draws. Also, consider the mana curve of your deck – having a variety of low-cost and high-cost cards can help you adapt to different situations during a match. Don’t forget to include some removal and card draw options to handle threats and keep your options open. Experiment, refine, and most importantly, have fun mastering the art of deck-building! May your opening hand be ever in your favor!
