Hey fellow Planeswalkers! When building your deck in Magic: The Gathering Arena, always remember to have a good balance between creatures, spells, and lands. Make sure your deck has a clear strategy and focus on cards that work well together. Don’t forget to include some removal spells and ways to deal with different types of threats. And most importantly, playtest your deck to see how it performs and make adjustments accordingly. Good luck and may your opening hand always be a keeper!
