Hey fellow Planeswalkers! When building a deck in Magic: The Gathering Arena, always remember to have a clear strategy in mind. Whether you’re focusing on aggro, control, or combo, make sure your cards work well together to support your game plan. Don’t forget to include a good mix of creatures, spells, and lands to ensure you have the right balance of resources. And most importantly, playtest your deck against various opponents to fine-tune it for different matchups. Happy brewing!
