CXyz Skypalace Babylon

[Toffee.]

3 Level 11 monsters
When this card destroys a monster by battle and sends it to the Graveyard: Inflict damage to your opponent equal to half the original ATK of the destroyed monster in the Graveyard. If this card has "Skypalace Gangaridai" as an Xyz Material, it gains this effect.
● Once per turn, if this card destroys a monster by battle: You can detach 1 Xyz Material from this card; it can make a second attack in a row.

Lets be honest, this card can do a ridiculous amount of damage; 1000 from Gangaridai(Assuming you Rank-Up this card in the same turn), then an additional X-damage from the difference between this card's 3800 and whatever the Opponent has, then more damage due to it's half-Flame Wingman effect, then even more damage from the fact it can make a second attack because it destroyed something, to which said second attack has no drawbacks or anything to it, and also potentially triggers it's 1st effect yet again.
The catch? You have to Xyz Summon a Rank 10 monster in the first place, for you to Rank-Up, which is rather uncommon for a deck to do.
But aside from that, you basically control a walking OTK. And it's cool, because it can still function with or without it's Xyz Materials.

It's one of the few CXyz whose effect is actually worth ranking up over itself, it's just Rank 10 is so unweildly as it is the lack of a RUM searcher jsut does it in.

 

Which is a shame because it's really good as just a beater to wipe out your opponent in a turn or two like you said. That and it can either decide to laugh and wall out Obelisk (For no reason other than to be a pain), or just run over anything else smaller than that.

Thankfully Gustav Max and Gangaridai are both viable for this thing, but until a RUM-searcher exists it's another "good but unwieldable" card.

[Wildflame]

If you manage to summon it, you OTK. That's pretty much it.

After pulled one too many from my NH box, I decided to build a deck focused around summoning this. Managed to win several times with the rank 10s but never got to summon this. I still want to use this well.

Really, rank-ups just need something that can search for rank-up spells (or traps if we get them, though as traps they would be far less effective), and they could be viable.

[Zeppeli Gyro Supreme]

It's the most powerful vacuum cleaner in the game, undisputed.

It's the most powerful vacuum cleaner-

Actually it's a giant cannon.

[Zeppeli Gyro Supreme]

Actually it's a giant cannon.

I was making a joke.

[TheTurtleOnceCalledGod]

Why can't it be both?

[Strider Tigerwolf]

Babylon can be made with Phantom beasts. I've made one after another in two consecutive turns before I drew into slipher. Was fun. Rum just makes it okay though...but the fact that even with lance itsna 3k burn+beater....and you got same hing potently nasty.
