Hey fellow Planeswalkers! When building a deck in Magic: The Gathering Arena, always remember to stick to the 60-card minimum to ensure consistency. Focus on a specific strategy or theme to make your deck more cohesive. Don’t forget to include a good balance of creatures, spells, and lands to increase your chances of drawing what you need. And most importantly, playtest your deck against different opponents to fine-tune it for competitive play. Keep slinging those spells!
