Aggro
Aggro (short for "aggressive") decks attempt to reduce their opponents from 20 life to 0 life as quickly as possible, rather than emphasize a long-term game plan. Aggro decks focus on converting their cards into damage; they prefer to engage in a race for tempo rather than a card advantage-based attrition war. Aggro generally relies upon creatures as its accumulative source of damage. Aggro decks can quickly overwhelm unprepared opponents and proceed to eke out the last bit of damage they need to end the game. Aggro decks also generally have access to disruptive elements, which can inhibit the opponent's attempts to respond.
