The only model I just had to assemble right away (and the only one I’ve already posted on the old forum) is the Sorcerer-Prophet (Lost Kingdom Miniatures) on Lammasu (Raging Heroes).
It’s great model and was fun converting a little bit, I magnetised the whole thing to also use the Lammasu unmounted or with the original Manticore head (not that I have a way of actually using it in a game)
