Is Wish the best pick for a genielock?

An Augury is not just that. IRL. Simple rules. The rules, the text cannot cover 100% everything about receiving an Omen.

Augury is also a divination, occult, astrology. As someone mentioned, in medival-fantasy circumstances - people where seekings omens, fortune tellers before they made important decisions.
And when that events, rituals where taken places, what was always important the person intention who received the omen.

Intention like his/her whole intentions. And you got an omen for that. And if You can cast the Wish, and you will loose it, that cannot be entirely good for you, even if your wish will be absolutely fine without any problems. You cannot separate that.

And this is also not just about the rules wording. The Augury effect not only for the wishing itself, or to loose the spell.
Metaphorically this is a whole together, regarding the omen. And cuz that event is a specific course of action, our intention will be that.
If you loose your wish but the wish itself will be good, that cannot be only good for you, with good omens. This is good and bad for you.
Still, the the final words is in the DM hands. And the omen is not a revelation, it can change.

The Augury doesn't take into account any possible circumstances that might change the outcome, such as the casting of additional spell, gaining or loosing companions. Augury, an Omen can help, but it won't be foolproof still.

oh i see...trying to get around the 1/day limitation on augury with a wish. thats fair.

I think someone else suggested that. I'm not really sure that's worth the risk of losing Wish forever.

but that still doesn't refute the rest of what i said, that augury itself doesn't allow you to determine if casting wish is going to result in you losing access to the spell. The information you get isn't specific enough.

Indeed, all Augury can tell you is if your Wish will come true in the way you want it to, or at least in a way that benefits you. If you wish to become immortal and the wish turns you into a stone, that's not good for you, and the Augury would only give you Woe. So it seems the discussion has shifted towards using Augury to double-check your Wish before you make it just to make sure it doesn't fail entirely or give you some monkey paw BS.

Augury can't predict future dice rolls (mostly because that's impossible to implement mechanically short of making those rolls ahead of time as with Portent). In fact, it doesn't seem to predict the future at all. What it does do is have perfect knowledge of the present and use that to calculate the likelihood of an action succeeding. Because again, those are the limits of the system and the DM can't actually predict the future.
