Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, one trick I swear by is always having a game plan. Whether you’re focusing on aggro, control, or combo, make sure every card you include serves a purpose towards your win condition. Don’t just throw in cards because they look cool – think about how they fit into your overall strategy. And don’t forget to playtest your deck extensively to fine-tune it for maximum efficiency. Happy brewing!
