I am not a Kess player and I come from a less powered up pod, but I think maybe it would be good to have different variations regarding powerlevel on this one. For the most part, I would tone the counters down to 4-5. If you play high power, then I would look for more tutors instead. One that comes to mind that works really good with Kess (depending on how fast or how much interaction your pod plays) is
Oriq Loremage. Also in casual it is better to have less counters. One thing is to protect your gameplan, but usually nobody likes to get their things countered, so if you play that high number, you will likely paint a target on your back without having any defensive support (creature tokens like with
Murmuring Mystic) or stax pieces like
Propaganda to give you a little bit of breathing room. Hope that helps
