An old adage in Magic The Gathering circles is Red Deck Wins. This is a comment on the ubuiqity and consistency of mono red aggro decks throughout a range of formats and over time.
urrent behemoths of the standard ladder (plus the ever growing contingent of white weenie decks) may seem laughable, until you change your focus on the win condition.
The point of this deck is to control your opponent with efficient creatures and spells that not only prevent, disrupt or payback their plays but also setup damage dealing sources that improve over time.
The point of this deck is to venture into the dungeon as frequently as possible, leading to greater card selection, control and card + board advantage. A range of decent bodied creatures, buffed by the completion of the dungeon are then in a position to finish off the opponent.
If you play your cards right (and get lucky with your draw), this combo can infinitely repeat itself, guaranteeing a win. The problem is setting it up and surviving while you do.
