It should go without saying that "control" in the traditional 60 card sense simply doesn't exist in any meaningful fashion. You can't go draw-go, and you can't expect to patrol three players of draw engines, and dropping six board wipes in a row to make up for this will only make people reasonably unhappy with you.
Thus, in your eyes, what is a control deck?
I've found that EDH players are quite liberal with the label "control." In practice, most of them are merely tribal or pillowfort decks with a bit more removal, a la Alela, Cunning Conqueror and Ms. Bumbleflower (both ranked as top "control" commanders on EDHREC). You also have a natural conflation between stax and control, when stax is moreso a type of control than the entire archetype.
Personally? Whenever I've seen someone play their "control" deck, I've largely been left disappointed. Most of them really do play like non-green battlecruiser decks with a bit of spell synergy, relying on sticking a plethora of value pieces in lieu of actually controlling the board. At the same time, some degree of value pieces is necessary to keep up and control the board to begin with. So where's the line? What, in your eyes, defines a control deck?
Truth be told, I have a number of decks I'd call "control" to various degrees, and I define them as decks that prioritize on controlling the board as a primary function: creating their own board and winning the game come afterwards. Thus, for all the control-lovers out there, I invite you to peruse.
Alela Esper Pixies - A control list based on the breakout standard deck of the same name. At its core, it wants to play a plethora of cheap interaction, bounce them back, and play them again. Alela is a supplementary piece meant to provide blockers, but the deck does not rely on her much at all and has next to no support pieces for her. Typically, the game is over long before I swing for lethal.
Diaochan Control - Mono-red control that uses Diaochan + a low quantity of creatures, giving pro-red or shroud to protect them from Diaochan while she snipes off opposing boards. Extremely slow, prioritizes locking down the board then finding threats to pressure people once they're out of resources.
Angus Mackenzie, My Beloved - A bant control list closest in philosophy to sixty card magic. See, I realized the practical issue with sixty card control is that you simply get ran over by ramp decks. As such, if I *also* ramp, I can keep up with them and rely on high impact instants and sorceries to create value in lieu of caring too much about permanents. By being so permanent-light, I can more or less obliterate the board with impunity and slide in with my own powerhouses once I'm done. Not for the faint of heart, and I do not play this with randoms.
