Gitrog, Horror of Zhava

{"ops":[{"insert":"Hi, hi! So, I keep trying to look up Gitrog on websites like archidekt and moxfield to add him to my commander deck but for some reason he won't pop up. I keep seeing that he's banned but for some reason when I try to see WHY he was banned, I can't find anything. I even looked at the gatherer website and saw he wasn't even on the ban list? I'm so confused, Please if someone could explain or help me out then I'd be so grateful. Thank you for your time!\n"}]}
