The team was seeing companion decks have too high win rates, and they wanted to work on making sure things werent too repetitive
FYI: "Tournament-legal cards have a width x height measurement of 2.5x3.5, or 63.588.9mm. When it comes to the thickness, non-foil cards are about 0.012, or 0.305mm, thick. Foil cards, on their end, are a bit thicker as they have an extra layer on top of the card that creates that shiny, holographic look. When it comes to the corners of Magic cards, theyre rounded at a radius of about 0.125, or 3mm."
Not undeservedly so: it is true that many of these cards make excellent Commanders, after all
There is never more than one monarch at a time
While nothing to sneeze at and having only the one hoop to jump will make this card pretty good, I do wish it had done one more thing
Cards like Fleet Swallower and Mirko Vosk, Mind Drinker mill your opponents rapidly
