Hey fellow planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, I always start by identifying a clear win condition. Whether it’s through aggro, control, or combo, having a focused strategy is key. Don’t forget to maintain a good balance between spells, creatures, and lands in your deck to ensure consistency. And always playtest your deck to fine-tune it based on how it performs against different archetypes. Remember, adaptability is key in this ever-evolving metagame! Good luck, and may your opening hand always have the perfect curve.
