Hey fellow Planeswalkers! When it comes to deck-building in Magic: The Gathering Arena, I always start by identifying a win condition. Whether it’s through overwhelming the board with creatures, casting powerful spells, or outlasting opponents with control, having a clear win condition helps streamline your deck.

Next, I focus on synergy between cards. It’s important to choose cards that work well together and support your win condition. This could mean including cards that have similar effects or combos that can be game-changing.

Don’t forget about mana curve! Having a good balance of cards at different mana costs ensures you have plays throughout the game. And always remember to playtest your deck and make adjustments based on how it performs. Happy deck-building!
