Yes, sometimes I’ll turn off cards that I know I don’t want to cast right away. But other times you need to leave them enabled (for example, if your hand is: creature with 0/8 mana, buff with 5/5 mana, other stuff. If you make a match that could lead to a cascade and cast the creature, you need the buff enabled so you can cast it this turn too; but if it doesn’t cascade, then you’ll just say ‘Not Now’ on the buff and it’s fine). Educating newer players about this functionality is important, but at this rate I’ll have dismissed this prompt so so many times by the time the next update comes out.
We’ve been on about this in the game since day 1. There are loads of threads in this subforum about it… look, here are a few:
