"You can also evolve the main deck in a variety of ways. If you max out with four copies of Grand Architect and add some bombs like Wurmcoil Engine and Mindslaver (and maybe a Treasure Mage or two to go find them!), you could be plopping giant monsters onto the battlefield as early as turn three. Alternatively, if you prefer a more swarming approach to combat, additional copies of Lord of the Unreal and Phantasmal Image can overwhelm your opponent with wave after wave of Illusions, while cards like Frost Titan stand by and mop up whatever's left."
