To be honest Wavesmith made it much easier to get into the Silver league. I played only 10-20 games there, but it get's much harder, as all fight are special fights (special rules, less teams) but it is a lot of fun as well :)
I created a small guide, how I played the game till now, I think this helps to get to bronze 1/silver 3... Usually I lost a lot of points because I wanted to do daily chests as well - https://peakd.com/hive-13323/@arkasz/my-starter-pack-strategy-on-splinterlands
