Great progress! I play in gold too now, although I pushed my way to champion a couple times but it required renting too many cards. I'm content in gold for the time being. I didn't pick up a Runi, and I haven't really regretted it because I usually end up beating teams with a Runi. I use a bot about half the time anymore because sometimes I just don't have time to play and it honestly has a slightly higher win rate than I do.
I'm hoping the SPS continues the climb since I've been accumulating a lot of it over the last couple years, and I agree things do look good!

I find gold a nice sweet spot, maybe I will try champion league one day, but I think it requires many maxed cards and I would have to rent probably like you said.
The SPS news is quite exciting. I usually sell SPS for DEC, so that would be exiting to burn instead and see SPS pump more. Great work stacking!
