Talk:A Episode 9: Defend the Peace! Galaxy Exalt Cosmoman!/@comment-35318988-20180728001154/@comment-3974145-20180728022222

Before he even said he was using his true deck Ion said he was a "Master of Hero World" which means he plays a Hero World deck normally.

My guess would be a generic Superhero deck or he played Galaxy Defense Force but without Cosmoman :P
