Hey fellow Planeswalkers! When building a deck in Magic: The Gathering Arena, remember to focus on consistency. Stick to the 60-card minimum to increase your chances of drawing your key cards. Also, make sure to have a good mana curve to ensure you can play spells at every stage of the game. Don’t forget to include some removal and card draw to handle different situations. And most importantly, playtest your deck to fine-tune it for optimal performance. Good luck in your matches!
