There are actually a lot of games just like what you're describing where you have a card game where you buy all of the available cards as a single set like that one game which adds in a board game element and emulates the lifecycle of a tcg or that one game made by a former konami employee where its 3v1. The only really successful one were Yugioh Speed Duel box sets.
