Thanks for sharing your article with us !
I'm quite surprised you are advising people to play Grixis Control to beat Miracles. Maybe were you meaning Grixis Delver ?
I felt like Counterbalance was a "one piece combo" to beat Grixis Control, besides I thought these Grixis don't put enough pressure on Miracles players to prevent them from settling a CB/Top lock (contrary to Delver versions).
You are of course way more experienced with Miracles than me.
