Not really; that's kinda dumb. Sure, Curlix is better than Burdock, but if you can spare the extra star (which he does), then there's no reason to pick Curlix over Burdock.
OP: If you can, you could swap Noodile/Burdock for Flora/Curlix and upgrade Pan to Mefisto. If you do that, you'll probably want a replacement for Artus to avoid too many defeat cards.
