Forum:Dark Law vs Super Transformation

My opponent controls Masked HERO Dark Law, Elemental HERO Bubbleman, and Masked HERO Dian. I control Ninja Grandmaster Hanzo and a facedown Ninjitsu Art of Super-Transformation. Can I use Super Transformation on Dian to summon a level 8 Dinosaur? Or do I need to target Bubbleman? Or is it illegal to Supertransformation when one of the cards will be banished?
