Fantastic !, I can't wait.
Anticipating these changes has already prompted me to buy some CL cards, looking forward to playing in Modern for the first time in months. After getting stuck in Bronze and being unable to claw out I just gave up after a few seasons of disappointment.
I think these changes will work well and foster play and card levelling
I'm guessing that is because human calculators that are scholaring for whales use their profits to make multiple accounts and then they camp out in the lower leagues. When I was stuck in bronze I saw accounts with the same name with different numbers at the end and I kept losing to them. I finally got out of bronze and I am currently bouncing between silver 2 and 1.
