Hey fellow Planeswalkers! When it comes to building a solid deck in Magic: The Gathering Arena, it’s all about finding the right balance of cards. Make sure to include a good mix of low-cost cards to start strong, some removal spells to handle threats, and finishers to close out the game. Don’t forget to consider your mana curve to ensure you can play your cards efficiently. And always playtest your deck to fine-tune it – sometimes a small tweak can make a big difference in your win rate! Good luck out there, and may your opening hand always have the perfect mix of lands and spells!
