Hey fellow Planeswalkers! When building your deck in Magic: The Gathering Arena, always consider your mana curve. Make sure you have a good balance of low, mid, and high-cost cards to ensure you have plays at every stage of the game. Don’t forget to include some removal spells and card draw to handle different situations. And most importantly, playtest your deck to fine-tune it based on what works and what doesn’t. Keep shuffling those cards and may your opening hand be ever in your favor!
