This is a Blue-Eyes Invoked list. This is probably one of, if not the, best budget variant of blue eyes, maybe not this build specifically. This build was made very neutral, without a specific meta in mind (also the reason I didn't include a side deck). So it can be modified easily to fit the current meta. This version does solve one problem the primite version has, and that's nibiru. As this deck can get out mechaba on it's third summon, as long as you have another monster in hand, nibiru can't hurt you (as much as it would without mechaba). It also of course helps you can make the blue-eyes link 1 with aleister. So just normal Aleister, search Invocation, link into spirit, do the normal things with spirit, and then go into mechaba with both aleister and spirit in grave. Hope you have fun with it.
