Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, I always start by identifying a win condition. Whether it’s overwhelming with creatures, burning opponents with spells, or milling their library, having a clear win strategy is key. Don’t forget to balance your deck with the right mix of creatures, spells, and lands to ensure consistency. And always playtest your deck to fine-tune it for different matchups. Remember, adaptability is key in the ever-changing meta of MTG Arena! Keep shuffling those cards and may your opening hand always be favorable!
