Saban's Tenko and the Guardians of the Magic

it's very possible that disney still has the rights to this series but it, alongside most of the saban back catalogue (excluding anime dubs/power rangers and other toku series/the cinegroupe collabs since disney no longer has the rights to these) has been neglected over the years by disney and as of now they have no plans to add them to disney+/hulu 8( 

Update regarding episodes 10 & 12:
The Jewel Riders archive on youtube responded in the comments of one of their reuploads that: “Yes. We have one of the two missing episodes. It isn't good quality but it's something; will be shared soon The best shared episodes are available on this playlist. These episdoes are rips from the DVD. We have all the merchandise including some production artwork. Stay tuned to JRA for more content.”
The episode that JRA has hasn't been posted yet, but hopefully soon it will be and then we'll have only one more episode to find (although the quality might not be very good, it's better than nothing.)

In my initial post I wrote that Cree Summer did the voice for Tenko but I was mistaken, Mary Kay Bergman was the voice actress. She’s most well known as also voicing Cartman’s Mom in South Park (unfortunately on November 11, 1997 she passed away.)
According to this article ( animeanime.jp/article/2005/03/16/181.html ) the first time Tenko & the Guardians of the Magic was shown in Japan was in 2005 at a special event at a cafe’ called Trinity in Shibuya. This article also claims that there were 26 episodes created but everywhere else on the internet there are only 13 episodes documented to exist. It’s possible that this article is incorrect about that, though it’s odd that they would get such a detail wrong. The 13th episode does end on a glaring cliff-hanger though, so I wouldn’t be surprised if there were more than 13 episodes planned. It’d be interesting to find scripts or storyboards from those unaired episodes and see what the writers had planned for the show. There’s also no mention of if the show was shown in the cafe’ with a Japanese dub or subtitles.

Transcription of the text under this photo: “Amy Jo Johnson(left), best know as Kimberly, The Pink Ranger, hosts “Let The Magic Begin,” a special half-hour “sneak preview” on the making of the new nationally syndicated children’s series, “Tenko and the Guardians of the Magic,” schedules for broadcast the week of September 4. The new part live-action/part animated series from Saban Entertainment stars both the real-life international illusionist Princess Tenko (center), and her animated counterpart (right.)"
The half-hour TV special “Let the Magic Begin” hosted by Amy Jo Johnson is also no where to be found online. I don’t think it was ever released officially, so our best bet is to find a TV recording. The text under the above photo doesn’t mention what channel this special aired on, but I’m assuming it was on FOX, since the cartoon would also air on Fox Kids.

• “Let the Magic Begin” TV Special
• Episode 10: “Will the Real Tenko Please Stand Up?”
• Episode 12: “The Magic Skates”
• Mariko Itakura (Princess Tenko) A.k.a Mari Asakaze’s Idol music
  

• Existence Unconfirmed:
  
• Episodes 14 ~ 26
• Japanese Dub/Official Subtitles

Great find Zangril!
I still haven’t had any luck finding the special or the lost episodes yet. I think it’s only a matter of time (at least for episode 10 since The Jewel Riders Archive said they’re going to upload it soon.) Along the way I did find various links of interest:
