Even if it is only partly a deck builder that is ok. It shouldn't be a minor part but as long as the game depends on it to a certain extentent, that is fine. No points should be awarded for history or contribution to the general as a whole.
Think about it as every single one of these was released today. Only one can stay a game and the rest go away. If there have been expansions, that counts, pretend like all that content are options that are part of the base game.
Feel free to add your own option if you feel like something fits the criteria but is missing.
