Hey fellow Planeswalkers! When building your deck in Magic: The Gathering Arena, always consider your mana curve. Make sure you have a good balance of low-cost and high-cost spells to ensure you can play something meaningful each turn. Don’t forget to include removal spells and card draw to maintain control and consistency in your games. And most importantly, playtest your deck regularly to fine-tune it based on your matchups. Good luck and may your opening hands always have the perfect mix of lands and spells!
