They offer a ‘Mastery Pass’ which rewards you as you play. What I love most about the quests is it isn’t ‘win’ based. You could earn 500 coins for playing 25 lands, casting 20 red or green creatures or even attacking with 30 creatures. If you play your ‘daily’ goals it encourages you to step out and play decks you wouldn’t normally do so. I find MTGA rewards players just for having a go. To get more cards so you can build more decks you can earn them quite easily, without spending real money. When opening packs you’ll also earn ‘Wild Cards.’ These can be traded for any card of the affiliated rarity. Unlike in paper magic where one Mythic Rare card could be worth .25c while another is $250, in Arena all Mythic Rares are worth a Mythic Rare Wildcard! This makes competitive decks absolutely accessible for everyone as it isn’t locked behind a paywall.
The newest set to be released on MTGA (and in real, physical form for those who prefer it) brings us to the frozen plane of Kaldheim. The world is full of Norse based mythology to life which features Vikings, monsters and gods. There is nothing more metal than Vikings, so Wizards collaborated with various bands like Mastodon, Amon Amarth and Rhapsody of Fire to help promote and reveal cards before release. How cool is that? (There is a joke about swinging axes here but it’s lost on me). The set is incredibly fun to play and perfect for a first time player.
