Number 116 Language English Legal Formats Commander, Legacy, Modern, Vintage Not Legal Formats Alchemy, Brawl, Competitive Brawl, Historic, Pauper, Pioneer, Standard, Timeless Rulings (12/7/2018) You don't have to choose the name of a card that's still in your library, or even a card that's in your deck at all
For most of Mutavaults time in the current Standard, its been largely a luxury afforded to either mono-color Devotion decks or two-color control decks with tons of extra land, both of which can afford to skimp on colored sources to get access to the best utility land in the format
A common but small misplay might happen after you play your opening Supporter for the game
Maintaining the Scarlet & Violet example, a regular Booster Pack from that collection has a pull ratio of 4 common cards, 3 uncommon cards, and 3 foil cards (at least one of which will be rare, ultra, secret, or, hyper rare)
I would suggest throwing this card in an Alela, Artful Provocateur deck
