There's a secret crazy powerful deck you can make with this no one is playing for some reason.... lol That will be MUCH better once XYZ become a thing.
I was more just musing over how it seems others haven't noticed the great synergy, despite the archtype being popular.
Suppose I'll post it for those curious.
Dynatherium x3
Koa'ki Meiru Urnight x3
Koa'ki Meiru Crusader x3
Guldfaxe of the Nordic Beasts x3
Koa'ki Meiru Maximus x1
The Big Cattle Drive x3
Iron Core of Koa'ki Meiru x2
Diamond Core of Koa'ki Meiru x2
Oh yeah, whoops!
Obviously, add in some level 8 synchros. I run two Scrap Dragon, two Stardust. Thought Ruler Archfiend is another option, but the pack he's in kinda sucks.
You still seem deeply confused and mistaken. XYZ Dragon Cannon is a crappy old, highly specific monster from a defunct archetype no one was talking about or referencing in any way.
In real Yu-Gi-Oh!, XYZ (Or Exceed) Monsters are an entire extra new deck classification like Synchro Monsters, but with a rank instead of a level. Summoned by overlaying two monsters of the same level.
Uuuugh, commenting on this site is frustrating. First I can't edit, then it places my already excessive extra post it in the wrong place! Anyways, I didn't meant to come off so rude.
