Hey fellow Planeswalkers! When building a deck in Magic: The Gathering Arena, I always start by defining a clear win condition. Whether it’s overwhelming with creatures or a powerful combo, knowing how you plan to win helps shape the rest of your deck. Remember to balance your mana curve to ensure you have plays at every stage of the game. Don’t forget to include removal and card draw to handle any situation. And most importantly, playtest your deck to fine-tune it based on actual gameplay experience. Good luck and may your opening hand always be strong!
