Cassandra Nova vs Dreamslayer (Maxwell Lord)

DS when he body jacked Lord.

Who wins?

Feats for Max?

At his weakest, mind nudging J'onn without him noticing.

At his best, mind wiping everyone on Earth.

He needed blood to do it, because nosebleeds, but DS could use Max's power without the side effects.

Dreamslayer is a powerful telepath, too. With his power on top of Max's, they should stomp.
