Robosentinel

"Robot Sentinel" is an archetype which consists of Machine-Type monsters created by Feder373, which debuted in the Booster Pack Mechanical Empire. These monsters appear as robotic humanoids, troopers, turrets and other things which function is to serve as defensive forces that protect some places of the Mechanical Empire against enemy intruders. Many of these defenses trigger automatically while others are triggered manually. The effects of these cards revolve mostly around responding to your opponent's actions on the field and trying to get card advantage out of their moves and interrupting their combos.
