But if there's anyone who can make weapons that can transform/change, and make it awesome, even practical (for this show at least), it's Monty XD Even Jaune's weapon set does this a little, ie his shield folding/unfolding

And so far, my personal idea is that Cardin's mace's 'head' spins around, though for what purpose I can't guess at yet
