Hey fellow Planeswalkers! When building a deck in Magic: The Gathering Arena, remember to focus on consistency. Try to stick to the minimum number of cards (usually 60) to increase the chances of drawing your key cards. Also, make sure to have a good balance between spells, creatures, and lands to ensure you have options at every stage of the game. Don’t forget to include cards that can deal with different types of threats to increase your deck’s versatility. Happy deck-building!
