I like Mechaba so much, I decided "Why not put up a Mechaba with a Mechaba?" The idea is pretty simple - Between Aleister and the Hex-Seals there are a lot of copies of "Aleister" to fuse with. Power Bond can serve as a back-up for Invocation to make Mechaba, usually making Mechaba #1. Herz is the ideal companion here - Herz can add a Cyber Dragon to your hand from your deck when it goes to the GY to set up Fusion plays, but it gets better from there. Pitch it with Mechaba, and you can use its effect to pick itself back up, meaning one copy fuels a single Mechaba for multiple turns. Additionally, if Therion "King" Regulus is equipped with Herz, when Regulus sends itself to the GY you can search (or pick back up) a Cyber Dragon. So this deck always has fuel for Mechaba. That's literally the deck, set up 3 Negates, then later kill with Chimeratechs, or use Chimeratechs to break boards and then set up negates if you can't OTK. You probably can. I believe in you! Or just attack with Cyber Dragon!
