I still don't see why people enjoy control mirrors. The games almost always last to time and even then there could be no clear winner. How does this make magic more fun?
I enjoy playing control mirrors because, in my opinion, a control mirror is the most skill intensive match this game has to offer.
There are far more subtleties, nuances, timing complications, and tempo issues that come up in a control mirror that never come up in any other match. At any point, during any turn, the game can go to hell. If a control player's defenses are not up all the time, even if only for an instant, that player has just opened up a path for the opponent to play around the opponent's cards and resolve a key spell. In doing so that player has just found a pressure point, gained leverage, and made things happen. This is how a poor hand can overcome a strong hand, and why the control mirror is the one match that I feel truly is the best representation of skill a player can perform (in Constructed, at least).
Maybe that's just me, but other noted people have also said as such.
I'm not targeting you in particular, but i see this sentiment alot. Mostly it comes from people who play control exclusively. How much Combo have you played? How much workshops? What you say in the big paragraph above I think applies equally to intense matchups with any good type one deck, irrespective of archetype (except maybe aggro).
I have piloted Combo, Workshops, and lots of Drain decks in tournament top8s and in my view, Combo is by far the most skill intensive of archetypes. (I'm the guy who piloted mono blue at gencon!) Control mirrors require alot of experience to learn. But once learned, it's fairly intuitive. It's almost entirely about timing and knowing what you need to win (forward thinking). Combo requires a constant analysis that experience simply cannot provide in making optimal plays. But you also need all that experience as well. Also, combo usually has the greatest number of potential lines of play making it the most difficult to find the optimal line of play.
