Hey everyone! When it comes to deck-building in Magic: The Gathering Arena, one important trick is to maintain a balance between spells and creatures. Having a good mix of both can help you adapt to different situations during a match. Also, don’t forget to include cards that can deal with various threats, such as removal spells or counterspells. Lastly, always remember to playtest your deck to see how it performs and make adjustments accordingly. Happy gaming!
