Oracle's thematic amazing, and just goes to show how much untapped potential there is for new support niches. I completely agree that there needs to be a support who gets to play heavily with vision, and an oracle champion would fit perfectly. As for the kit, there's a lot of stuff I like (her mobile passive looks amazing, and I think it could be really interesting to give allies stealth), though also some effects I question, along with some more minor potential technical issues. Here are my thoughts:
 * I really like the idea of a champion being able to extend their vision range and deploy it around. There's a potential risk here for Oracle to just stand still for minutes-long periods and sweep the whole map to clear enemy wards, but the idea itself of projecting one's own vision sounds fantastic. I'm not sure what the basic attack and attack speed modifiers contribute to Oracle's kit, though.
 * I love the idea of granting stealth to allies, though the detection range confuses me: does this mean that you and your target ally are stealthed to nearby enemy champions, but can be detected by enemies from the other side of the map through wards?
 * Telempathy is my least favorite ability here. I'm personally not a big fan of Tenacity, as it devalues crowd control, and I'm not sure how the damage absorption would work out (if it redirects damage to Oracle, that might not be so good as she looks like a squishy utility support, and pure damage reduction isn't the coolest kind of power around). Potentially enabling URF mode on allies sounds hilarious and majorly impactful, though power of that level should probably be limited to a short duration on a long cooldown, rather than active on a persistent tether.
 * Psionic Blast's true damage makes sense for its long cooldown, but I'm uneasy about tying in an AP ratio to its stun, since past certain AP values you'd end up with pretty crazy durations (you could have a -second stun with just 400 AP, for example).
 * I think Omniscience could do with a bit of retooling. The instant-cast effect would be good in that it would allow Oracle to cast spells more quickly and move around, but would remove her primary counterplay (i.e. standing still and channeling), even with the delay to prevent E abuse. The doubled vision effect is great, though. Other than that, the early duration combined with Oracle's cooldowns means she'd only be able to use them for a single ability cast (which could be fine), but the increased uptime you'd get with AP and CDR means you'd be able to cast this with only a few seconds' downtime, which limits the amount of power you could have here. It would be interesting if Oracle could, say, project herself and her abilities to anyone in her vision range, but that would likely be too strong given Omniscience's overall uptime.
 * From a a gameplay perspective, I'd be apprehensive about some of the details in your kit: the long cooldowns means you might end up with nothing to do in the middle of combat for extended periods of time (by contrast, even a champion like, who has high cooldowns on her basic abilities, gets to use them every 9 seconds at most at full CDR), Oracle's kit doesn't really scale particularly well with level, she might suffer from issues similar to in that she has a damage curve that only increases five times (so maxing E in lane would cause her early damage to skyrocket, then abruptly slow down for the rest of the game, which would make her offensive power more difficult to balance), and her being manaless might strongly interfere with traditional support itemization, especially CDR itemization, which heavily involves mana and mana regen (it also means she could stay indefinitely in lane if she hangs back far enough, which could be possible given her vision and tether ranges). Ultimately, this is not as important as your core kit, but the numbers on your abilities might lead to some pretty weird cases.

Overall, there's a lot of core ideas here that sound amazing and fresh, and the fact that you've added AP scalings to even the more oddball components of Oracle's utility means she'd have a ton of unique incentives to build and scale well with AP. With that said, some of those numbers and effects look a little janky, and I think you could afford to have an ultimate that could be a lot more crazy and impactful, even if it would come at a greater cooldown. Overall, this is a good concept, but more importantly it's one that dares to add a ton of new effects and gameplay to a setting that, in spite of massive recent developments, still has a long way to go before doing anything interesting with certain mechanics, much less go balls-out on them, and so with minimal abuse potential besides number and minor tuning issues.
