Midrange deck
Midrange decks are aggressive decks that flip the standard Aggro-control deck archetype by attempting to control the early game, then going aggressive with large creatures in the mid to late game. Midrange typically features very few creatures in the 1-2 CMC range and instead tries to win with creatures in the 3-6 mana range while casting aggressive removal, board sweep, discard, and ramp cards in the early game.
A typical Midrange deck plays either Green/Red or Jund colors, as these colors provide the most options for aggressive creatures and aggressive removal.
