Hey fellow Planeswalkers! When building your deck in Magic: The Gathering Arena, remember to focus on synergy between your cards. Choose cards that work well together and support your overall strategy. Don’t forget to include a good balance of creatures, spells, and lands to ensure you have options in different situations. Test your deck in practice matches to fine-tune it before taking it into ranked play. And most importantly, have fun and keep experimenting with new deck ideas! Good luck out there on the battlefield!
