Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, one trick I always keep in mind is to maintain a good balance between creatures, spells, and lands. Having the right mix is crucial for a well-functioning deck. Also, don’t forget to include cards that can deal with a variety of threats to increase your deck’s versatility. Stay creative and experiment with different card synergies to keep your opponents on their toes! Keep slinging spells and may your mana never be color screwed!
