Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, it’s all about finding the right balance between spells, creatures, and mana curve. Make sure to have a good mix of early game creatures for board presence, removal spells to deal with threats, and powerful finishers to close out the game. Don’t forget to pay attention to your mana curve to ensure you can play your cards consistently. And always be on the lookout for new cards that can synergize well with your existing deck strategy. Happy deck-building!
