The Ninjago Legacy theme revisits classic Ninjago sets with updated builds and designs. Turning back the clock to Season 3, the 71704 Ninjago Legacy: Kai Fighter reprises 2014’s 70721 Kai Fighter, more than doubling that set’s 196 pieces to a much heftier 513 part count. This new version retails for US $39.99 | CAN $49.99 | UK £34.99 and is available now. Is it a worthy upgrade to the classic set? Come along as we run through the highs and lows of this new set!
