Control

A control deck is one of the three main types of deck. It is the opposite of a beatdown deck. A control deck intends to disrupt your opponent's behavior and gain complete control of the battle zone.

Removal control
A removal control deck is a deck that intends to control with spells. It mainly does this with cards that make your opponent discard, like Ghost Touch and Lost Soul, and cards that destroy your opponent's creatures, like Terror Pit and Apocalypse Vise. Of course, these decks tend to run quite a few blockers. To finally win the game, removal control decks usually bring out a finisher creature like Devil Diabolos Zeta, Evil Awakened or Bolmeteus Steel Dragon or make your opponent run out of cards in their deck with cards such as Volg Thunder and Yasaka Shark, Viral Torpedo.

Creature control
A creature control deck intends to control the field with creatures. Such a deck often aggressively removes your opponent's creatures either by using creatures with destruction effects like Olzekia, General of Decapitation and Punch Trooper Bronks or by forcing your opponent's creatures to battle with your creatures with cards like Smash Warrior Stagrandu and Miele Thunder, the Gemwing. After gaining a large field advantage over your opponent, a creature control deck usually breaks all of its opponent's shields at once then attacks to win.

Mana destruction
A mana destruction deck wishes to control its opponent by getting rid of the cards in their mana zone. There are many ways of doing this; Mana destruction decks tend to be disadvantageous against beatdown decks, especially rush. Also, Terse Ruth, Lightboom Guardian and Snork La, Shrine Guardian tend to make most mana destruction ineffective if they are not removed quickly.
 * Combining mana destruction with removal control
 * Using a one-shot powerful devastating mana destruction card like Überdragon Bajulaterra and Hydro Hurricane
 * Focusing your deck on the mana destruction with cards like Simian Warrior Grash and Admiral Queen

It is not necessarily true that these three types are completely separate; they can and will intertwine.
