Wind-Up Level 3 good stuff

Its mainly to preserve your normal summon so that you can have an extender if zenmaity gets negated. All the stuff here is so that you can keep your normal summon for later plays. Rescue cat is good without a doubt, but genex ally bird man and star beast are crazy. If you want to run rescue cat you can probably replace the junk forwards.

Why "Level 3 good stuff" when you're only running 1 rank 3? I don't really understand Wind-ups so educate me. Not even Zenmaines?

Level 3 good stuff is for turboing into zenmaity. The main deck monsters are all level 3 besides magician and shark(sometimes). The level 3 monsters are essential for getting into zenmaity without normal summoning. The level 3 monsters are also really fun with gallis, bird man and the dangers. Very fun deck

But you can only run Zenmaity at one, is there really no reason to not at least use one other Rank 3? Like you said, almost all the main deck monsters are level 3. I just thought it was odd most of the extra deck XYZs were rank 4s. It even looks like you're making your Utopic Future with rank 4s. I'm just a little confused. I thought Zenmaines was considered a really strong Rank 3 but it's also not here.
But I also don't play Wind-Ups. It does look very fun. I just want to understand.
