I wasn’t tripping! There’s a game with the exact concept of op in which you and a friend have to fight over who has the tallest tower using magic cards. I played this a lot as a kid and after making the deepest search of one (1) google search, i found it: the name’s Castlewars, and it’s on Kongregate.
ES6 will feature a quest featuring two wizards who live in opposing towers who both hate each other because the others tower is taller and they keep using magic to make their own taller. You can solve their issue in several ways. By killing one or both of them, or you can blow up both of their wizard towers so that nobody has the tallest. Or you can join in on their pettiness and build your own very tall wizard tower.
