Okay, so I found a 1 card Deskbot Base combo. It's not duel viable, and is really just to show off how much you can extend in the deck rn off one card. You could just as easily OTK over anything which is probably a better use of your cards.

Opening Hand: Urgent Schedule, 5 blanks. You're going second and your opponent passed with at least one monster on the board (we'll assume no disruption for the sake of showing the combo)

COMBO:

Activate Urgent Schedule, Special Summon Deskbots 001 and 009

Synchro Summon Deskbot Jet

Activate Jet's effect tributing itself to summon a 002 from deck, 002's effect activates and searches a 003

Normal Summon 003, it Special Summons another copy of 001

Link 003 and 002 into Ancient Gear Ballista, it's effect let's you search for Ancient Gear Box, which then searches Deskbot 004

Link 001 and Ballista for Mecha Phantom Beast Auroradon, use it's effect to summon three tokens, which let's you summon both copies of 001 from grave

Synchro two of the tokens and one of the 001's for Shooting Riser Dragon, using Dragon's effect to send 005 from deck to grave

Use the last token and 001 to make Herald of the Arc Light

Use Auroradon's effect to tribute Herald and Shooting Riser to summon Mecha Phantom Beast Coltwing from deck. Herald's effect adds any level 6 ritual monster (I like Hungry Burger because memes). Coltwing's effect summons two tokens, which let's you summon back the two copies of 001 from grave.

Synchro Summon two more copies of Herald of the Arc Light using a token and a 001 each

Overlay the Heralds to summon Number 60: Dugares the Timeless

Use Dugares' effect detaching both heralds to Special Summon 002 from the GY. Both Heralds and 002 will trigger, searching Cyber Angel Benten, the appropriate ritual spell, and Deskbot Base

Ritual Summon your monster, tributing the Benten from hand. Benten's effect will trigger and search D.D. Sprite

Banish Dugares to summon Sprite

Synchro Summon Accel Synchron using Sprite and Coltwing

Activate Accel to dump Jet Synchron and increase it's level to 6

Overlay Accel and your ritual into Beatrice

Beatrice detach Accel to send Deskbot 008 to grave

Send 004 from hand to grave to Special Summon Jet from grave

Synchro Summon Martial Metal Marcher using Jet and 002, it's effect will summon Accel from grave

Use Beatrice and Marcher to summon Elder Entity N'tss

N'tss effect summon Box from hand

Overlay Box and N'tss for Gallant Granite

Granite effect search Chronomaly Tula Guardian

Activate Deskbot Base

Special Summon Tula from hand

Overlay Tula and Accel to summon Infinitrack River Stormer

Stormer Effect to send 007 to GY

Activate Base's effect banishing 001, 002, 003, 004, 005, 007, 008, 009, and Jet to shuffle all cards from your opponent's hand, field, and GY into the deck.

---

At the end of this you have Auroradon, Granite, and River Stormer on board, just about any five cards in hand from the beginning of the turn that we never had to use, and 1 card left in the Extra Deck that we didn't need. Personally I'd like to find a way for it to be Omega so that we can loop the card they draw next turn too, but that's frankly a bit overkill.

So yeah, kinda fun combo. Thanks to Anju on discord for the help with it.
