Probably the same things as we see in the manga.

Spoiler for Manga:

Baba Yaga is being attacked, so we'll probably black star coming in being able to use three forms of Shadow Star Chain of Blackness, Severed Shadow, and Branched Darkness.
As well we'll probably see him using Soul Authority (Soul Purge or Soul Threat for those of you who still trust fansubs/scanalations and their crappy translations). And his own Planet Destruction Cannon.
