Ivy has always been difficult to deal with in SoulCalibur. Her ranged game coupled with her grabs make her even more dangerous in SoulCalibur VI, and this video makes it look even crazier.
Not only does Telethon show grab setups off of hits with some of her best buttons, but he also discusses how to mix up your grabs with other follow-up buttons to keep your opponents guessing on whether to tech the throw or not. It becomes a difficult situation given either way you go, you are going to get a large amount of damage if they guess wrong.
