For me, I went between Tasslefoot and Pastoo selling bronze, silver and diamonds. Soon you'll have 1mil++. I found it pointless buying anything other than a vanguard, so saved up 18-20k and bought one.
19 -> Flowers, Cap, water until bottom flowers are dead, take off cap, water once, put grass seeds, water again.
20-> Black paint, cap, yellow paint, take off cap, rotate, put on cap, yellow paint
Repeat until black portion is right size and rotate to match picture.
I liked it, but I'm not sure if theres a way to finish dragon tamer. As soon as I was 17, I went Tamer>Tamer>Forest Holiday but the max I could get was 71.4
