In MTG Arena, the Vault is a way to reward players for collecting duplicate cards. Every time you get a fifth copy of a common or uncommon card, it contributes to your Vault progress. Once your Vault progress reaches 100%, it opens, and you'll receive three Mythic, two Rare, and one Uncommon Wildcards. These Wildcards can be exchanged for any card of the corresponding rarity, allowing you to fine-tune your decks!
Eh, the Vault's not all it's cracked up to be. It takes forever to fill, and the rewards aren't as exciting as pulling a great card from a new pack. Better than nothing for your duplicates, though.
