Shock and Grasp of Darkness cant remove it, and although Harnessed Lightning and Fatal Push can, both have to jump through hoops to do so
Conversely, this deck is designed to put pressure on your opponent and force them to continually clear your board, so it doesn't have any removal tool of its own
Some characters will have their own effects that only trigger when those characters are at locations, like Peter Pan, Lost Boy Leader, who will have you gain lore equal to a location's lore value the first time he moves to one each turn
Shes now a 6/6
Fortunately this is an ability with no range that can only be used by a certain class of Morbol and it can only be used when it's immediately adjacenet to a friendly unit with the Monster Skill support ability attached, so you'll never realistically actually run into an enemy Morbol that can use it, and even if it can be used, it has a very low success rate at that
