Used to run 4x
Akko, Inspired Artist instead of Kazuo, still testing. A 2/3 is pretty useful!
You can easily put a lot of pressure on the enemy quickly - most games are resolved by the 7th turn.
Galai, Shavka's Listener is a serious threat in Expedition, often they have to block since you are packing a TON of removal and probably took out their other blockers.
I've won games off the back of a processed
Jawbone Greatsword but it mostly functions as premium removal, they usually don't expect you to take out an x/5 in Praxis colors.
Have fun!
