I've ignored most of the Nexo Knights sets but 72004 is incredibly badass. It's got a Warhammer style power armor inside a mech! Got it for $32 on Amazon. : r/lego
LEGO NEXO KNIGHTS 72004 TECH WIZARD SHOWDOWN
We recreated set 72004 from our own, Nexo Knights-heavy collection. It's almost like getting a free set ;) : r/lego
