Hey fellow planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, remember to focus on a clear strategy. Whether you prefer aggro, control, or combo decks, make sure every card serves a purpose. Keep your deck at the minimum of 60 cards to increase consistency. Don’t forget to include a good mix of creatures, spells, and lands to ensure a balanced mana curve. And always playtest your deck to fine-tune it for different matchups. Happy deck-building!
