Nice items for AD-Sion:
Ravenous Hydra
Frozen Mallet
Maw of Malmortius
Mercurial Scimitar
Sword of the Divine
Youmuu's Ghostblade

of course not all of them in one build...

Create a new one. You can copy-paste material from the old one over to the new one if you want. See my Ten Commandments for more info (I think it's under Third Commandment)

If I archive it now, make some changes to it and everything can I republish the same guide or does it need to be done all over again. As you said I can always cut and paste but do I HAVE to do that?

I see two major problems with your guide. As outlined before stacking doesnt work. You could get a , replacing one of them and change your Tenacity boots. But the bigger issue is that with capped CDR your base mana pool will be too small on Sion, and without a single mana item, you cant use your abilities.
I would suggest a more tanky buildorder and an added Catalyst the Protector:

Archiving keeps your build but makes it no longer accessible by search and no longer commentable. You can still copy-paste sections of it.

As a rule of thumb, there is only one stackable item in the whole game and that is Bloodthirster. Instead of 2nd nashor's, get Zephyr or Wit's End. Instead of 2nd PD, get Zephyr or Statikk Shiv.

Okay, thanks for the advice and not ripping me to shreds. I now see where I went wrong and probably published this guide before it was ready, I kinda knew it would be a work in progress but didn't note that in my intro. I do need to remove that 2nd Nashor's tooth (I feel like a dumb) and build it into a Zephyr or something instead. I plan on making some revisions (a lot of them actually) and republishing. If I archive it does it banish it forever or can I edit it and reuse most of it? Should I just leave it up and keep editing it?

First, this is more so Hybrid than AD. Just wanted to say that.

Second, Nashor's and Stingers don't stack with each other. You're wasting the CDR from them.

Third, generally stacking anything without good reason is bad. The second Nashor's and the second PD could be replaced with defensive, offensive, or hybrid offense-defense items like Maw of Malmortius or Frozen Mallet, or heck, seeing as this is hybrid already, Trinity Force. If something says "UNIQUE Passive," that means it won't stack with itself or other items with the same passive name.

Also, have alternatives; following the same build every game just doesn't work. You need to be able to adapt.

Finally, we need info on how to play, on how to work with teammates, what he's good with and against, what he's bad against. Use a bit more formatting for prettiness's sake. Yes, it makes a difference in your rating.

I suggest not writing another guide for quite a while, wait until you have a lot more experience in the game. Learn everything about what you say, and make sure that you are correct.

Double Nashor and double PD? You know nothing about the game. Please archive this guide, and do not write any more.

I think that maybe you should get at least one defensive item such as Frozen Mallet or Guardian's Angel, because if you get cc'ed you won't have a chance to use your life steal. Also, since Sion can gain infinite health I suggest an Atma's Impaler.

what's missing is that nashor's dont stack....y 2? y nashors? y no zephyr?

Hey! This is really promising for a first guide, I just feel that someting is missing.
Why full offensive masteries?
How do i play sion? What about lategame? Why Don't i go tanky?
When do I pick sion? Why do I pick sion over someone?
