Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, remember to have a clear win condition in mind. Whether it’s overwhelming your opponent with creatures, burning them out with direct damage spells, or outlasting them with a control strategy, make sure every card in your deck contributes to this goal. Don’t forget to include a good mana curve to ensure you can play your spells consistently. And always playtest your deck to make adjustments based on how it performs. Happy brewing!
