Ironically MTG is the least likely to have a deck that overwhelms all others. Perhaps that is because they release a base set and three sets in the current play block about every 10 months. When you release that huge volume of cards then the game will be more fluid. It is almost like they keep people from settling on one deck type because there are so many cards constantly coming at them.
Not to mention set rotation, and the ability to print counters. All of which keep people buying cards....
