Hey fellow Planeswalkers! When building your deck in Magic: The Gathering Arena, always start with a clear game plan in mind. Focus on a specific strategy or synergy that you want to build around, whether it’s aggro, control, or combo. Make sure to include a good mix of cards for early game, mid game, and late game to ensure you have options at every stage of the match. Don’t forget to regularly review and refine your deck based on your gameplay experience. Happy brewing!
