Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, always remember to have a good balance of cards in your deck. Include a mix of low-cost cards for early game advantage and high-impact cards for late-game power. Don’t forget about cards that can deal with different types of threats, like creature removal or counter spells. And most importantly, try to stick to the 60-card minimum to maximize your chances of drawing your best cards. Keep shuffling and may your opening hand always be in your favor!
