We are sure you’ve already seen the official Wizards of the Coast announcement on this, and other community formats around the world including the Commander Rules Committee:
“Effective June 10th, 2020, Wizards of the Coast is removing seven cards from all their constructed formats. We support the message they are sending through this action, and stand with them in attempts to foster a more inclusive and positive culture.”
We could re-write this statement, but there’s no need; we also support this action and will be following suit.
These cards are removed from all constructed formats, including 7 Point Highlander.
