Manifested Dragon Lord Ojutai

[Noblellama]

If I manifest {Dragonlord Ojutai} with {Cloudform} and flip him, what happens to my aura?

What about each time he untaps?

It'll stay attached, like it would to anything else you flip face up with it.  He'll constantly have hexproof, because an effect is granting it, regardless of whether it's his own or the Aura's.  Now, if Dragonlord O normally had Hexproof and his ability said "[This] loses hexproof as long as it's tapped", then it would turn off and on as normal, since an effect is causing him to lose it, not gain it.

So is this similar to my {Pristine Angel}s? or does their protection function differently than his hexproof?

And other than equipment is there anything else I can sneak onto an {iridescent Angel} to make her more dangerous?

Hex proof prevents targeting by opponents. Protection prevents damage, targeting, blocking and enchanting.
They are two different keywords.

As for Angel, protection from all colors will prevent any colored enchant from sticking. You can't target with the aura spell, and even if you sneak one on with say {crown of the ages}, it would unattach because of protection.
In he case of hexproof, your opponent could use this method to {pacifism} your Oji

EDIT: I know, crown says the new enchant must be legal, so you couldn't move with crown, but it's an example of a way that doesn't target.

So I can sneak auras onto Ojutai and when he untaps im already inside his "shield", but if I do that to the pristine angel her "armor" pushes the aura off because protection (armor) is better coverage than hexproof (shield) basically?

Exactly. Though, hexproof only stops OPPONENTS from targeting. You can target your own Oji.
Shroud is the one that says [permanent] can't be targeted.

Load dat angel up with equipment! She looks strong. I bet she carry quite a few swords.
Wait, could you do {godsend} or her? Would that be considered a white source?

Edit: never mind, didn't see the "other than equipment" part.

its ok, I think godsend has a color of white and hence cant be equipped to her naturally, but I think I can sneak it onto her with the little artifact guy {Brass squire}?

Nope, part of Protection is preventing things from being attached, as well.  There's no way to sneak colored things on to something like Etched Champion with Metalcraft or the Angels.
