The Magic: the Gathering Standard Best of 1 Format in Magic Arena is one of my preferred modes because of the lack of card components in my original account’s card pool. The advantage is if you win, the opponent has no chance to get back with the sideboarded games. That is also the drawback if you get to face a deck that has more edge than your build. Anywho, I can say that this is the best mode to grind fast your rank if you get to build the best deck fitted for the BO1 gameplay.
For today, I have this Standard BO1 deck feature that has probably filled with utility cards for any metagame deck matchup in the format. In what way that it can perform 100% but in a Control shell with, of course, the three best colors in Magic for the archetype: Esper.
Check out this Esper Control version for Magic Arena Standard BO1.
