Nice review!
I started similar than you almost 4 years ago and since I have built a nice amount of SPS (even sold some 😏), but right now I lost faith in cards, because they lose value very badly... I do not really dig myself deep in lands, but I have 2 licence, which works pretty well generating some SPS even though I do not understand what they really do! :)
Anyhow I liked your post a lot and have a lovely day! 😉
