Hey fellow Planeswalkers! When building a deck in Magic: The Gathering Arena, always start with a clear strategy in mind. Whether you’re going for an aggressive red deck or a control-based blue deck, make sure every card choice serves your overall game plan. Don’t forget to include a good mix of creatures, spells, and lands to ensure a balanced and consistent deck. And always playtest your deck to see how it performs in different matchups. Happy brewing!
