Here is the latest MTG Arena data fetched straight from our extension MTGA Assistant. Last update we talked about getting Brawl metagame into the mix and here it is. With our recent update released today we pushed out a companion update, so we will be able to import companion data and group them separately from now on. Instead of naming the companion decks after their color as we do now, they will be named after the companion. Expect this change on the site within a week, we need to gather data and test that everything works and then update some of the already posted meta decks containing Companions.
Let us get into the metagame, the percentage shows how much of the metagame that specific deck covers, while the number is how many decks this is.
