Deck Idea: Wind-up and Koa'ki Meirus

I'm pretty inspired right now, so I won't write alot, just something to let you have an idea of what i'm going to build.
Basically, if someone remembers it, I wrote a post about Koa'ki meirus and how they have swarm potentials. I thinked about wind-ups because they have a lot of power and are a meta deck in this metagame. They can swarm R3 xyz, this mean you can even summon M-X-Saber Invoker (I talked about him in the Koa'ki Meirus post).
Basically then, let your wind up combo work and, when you are going to do the last xyz monster you can do, summon invoker instead of zenmaines. Use invoker's effect to summon urnight from the deck, and use his effect to summon another koa'ki meiru, preferably crusader. Now you can XYZ into emeral and recycle your monsters, or XYZ into utopia to have a beatstick and a 2 times attack negation effect, or into steelswarm roach to mantain your control over your opponent.
I'm going to build this right now, one of these days i'll talk deeply about this, if it works.

Koa'ki Meirus

Who are koa'ki meirus? Koa'ki meirus are an archetype i always loved, even if i can never get it work, but i was young and newbie, if not noob. They have powerful effects (looks like an advertise from konami) but difficult to mantain, because they need either to show a monster with the same type (usually, but sometime even a trap or spell card) or discard an Iron Core of Koa'ki Meiru in the end phase to stay on the field, which makes them weak because that'll slow your deck (because re-add iron core from grave will cost you your draw phase) and instable. A lot instable. We saw them played only in Rock Antimeta (only few of them), Hopeless (only Drago) and in Gallis FTK (even if only doom gets played in there)
If they suck, why am I writing about them, then? Because XYZs power-up everything.
An XYZ summon will take the koa'ki meirus off the field before they must pay their maintenation cost in the end phase.
Let's see them and focus on the needed cards.
