Quote from IronPlushyLast rotation I had to aggro out in a control mirror and ended up winning because I realized I was the aggro player. Haunted Plate Mail on my Augur of Bolas or Restoration Angel was too much for him to handle.
It becomes very interesting when your control deck is capable of aggroing, I think in the control mirrors currently by the time you assume the role as the aggro or control player it's already too late since control decks are so similar and the most controlling player wins.
That's a pretty well-known bit of Magic theory. The basic question of any matchup is "who's the beatdown?" One deck is the aggro deck, and one deck is the control deck. This applies in literally every game. Control matchups have to determine who's the more aggressive of the two. Aggro matchups have to determine which can outrace the other, and which has to slow the other down. Misassignment of role there is frequently a game loss.
