Imo these are the best Ninjago sets (not including the Old Town and Ninjago City sets because that's plain cheating XD)

(note this is not in any order) Quick reasoning Ninja Character Display - because it has all six Ninja, Wu and an Elemantal Master from the Serpentine War for such a cheap price, you can even mess around with the Display and put whoever the heck you like! Four Weapons Blacksmith - practically perfect, wished Kai had a better hairpiece and I think some Skeletons would be nice Source Dragon of Motion - because she's a BEAST of a set Dragon Stone Shrine - maybe the Minifigure selection is meh...
