There are definitely some stand-out disguise cards, which might be problematic, given the whole disguise thing
Terra, Herald of Hope Terra, Herald of Hope is a solid commander with a neat combo built in
Its the type of commander that you can get out early and likely wont be removed right away, so it can probably do a decent amount of damage
