Hey fellow Planeswalkers! When building a deck in Magic: The Gathering Arena, always start with a clear strategy in mind. Whether you’re going for an aggro, control, or combo deck, make sure your cards work towards that goal. Don’t forget to include a good mana curve to ensure you have plays at every stage of the game. And always playtest your deck to fine-tune it – sometimes a small tweak can make a big difference! Happy deck building!
