Hey fellow Planeswalkers! When building a deck in Magic: The Gathering Arena, always focus on a clear strategy. Whether you’re going for aggro, control, or combo, make sure every card you include serves your game plan. Don’t forget to consider your mana curve to ensure you have the right balance of spells for each turn. And always playtest your deck to fine-tune it based on how it performs against different archetypes. Good luck and may your opening hand always have the perfect mix of lands and spells!
