Hey fellow Planeswalkers! When building your deck in Magic: The Gathering Arena, remember to have a good balance of cards for early, mid, and late-game strategies. Make sure to include removal spells, card draw, and win conditions to have a versatile deck that can handle different situations. Don’t forget to playtest your deck and make adjustments based on how it performs. And most importantly, have fun strategizing and outsmarting your opponents on the battlefield! Good luck, may your opening hand be ever in your favor!
