Hey fellow Planeswalkers! When building a 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 synergy between cards. Don’t forget to include some removal spells to deal with your opponent’s threats. And most importantly, playtest your deck to see how it performs and make adjustments accordingly. Building a strong deck is the key to victory on the battlefield! Keep slinging those spells and may your opening hand be ever in your favor!
