With so many "partners" yet be spoiled in Commander Legends, mixing and matching at this stage seems a bit premature, but these guys are obviously worth combining for a flying and scrying build around.
I guess the first thing to point out is that there are actually no shuffle effects in this deck. No searching at all.
So you are guaranteed to be able to scry things on to the bottom of your deck and know that you won't be drawing them.
In this way the deck is very good at digging through your deck to get to cards that you want.
The deck attacks (pun intended) on various levels. It is filled with flying creatures and a lot of them are low cost to cast so that you can curve out into Siani and Eligeth filling the skies to be able to get great advantages.
The idea is that you can scry through your library to find sets of cards that are going to help you at various stages of the game with Siani, Eye of the Storm ability.
Then once you are able to successfully cast Eligeth you'll be able to draw cards equal to those scry's instead.
The deck has lots of scry outside of Siani ability as well. Lots of the flying creatures themselves have in built scry. Imagine with Eligeth in play that you get to draw each time you trigger these.
Artificer's Assistant for each artifact, saga or legendary you cast.
Faerie Seer, Augury Owl, Stormwing Entity each scry on ETB. Stormwing Entity can easily be cast for in this deck.
Sphinx of Foresight gives you a scry each upkeep.
Prognostic Sphinx gives you scry 3 each attack.
Curator of Mysteries is actually a combo card in this deck when combined with Eligeth and Mind over Matter. You can discard cards to untap lands and you'll keep drawing a card each time to keep being able to do this. As you'll get to untap mana sources you can keep digging for cards that draw you even more cards and eventually you'll be able to flood the board with a squadron of flyers.
Prognostic Sphinx can be used instead of Mind over Matter to keep discarding to draw with Curator of Mysteries and Eligeth allowing you to get to key cards.
There is also a instant and sorcery sub theme with some creatures that have synergy.
Docent of Perfection and Talrand, Sky Summoner can produce token flying creatures.
Ethereal Forager can be cast for a lot less with the delve and then get those instant and sorcery back for more value.
Prescient Chimera gives you more scry and with Eligeth straight up draw each time you cast an instant or sorcery.
Shark Typhoon will produce token flyers each time you cast a noncreature spell, and you can just cycle it to get a flyer as well.
With this there are a number of great instant and sorcery that have scry as part of them.
Mystic Speculation, Serum Visions, Preordain become an Ancestral Recall with Eligeth.
Deliberate, Scour All Possibilities draw 3 cards still (with Eligeth).
Opt round out this scry theme at instant speed.
Marit Lage's Slumber will allow you to scry or draw (with Eligeth) each time you play a Snow-Covered Island.
Medomai's Prophecy and Omen of the Sea are two great scry/draw enchantments.
Thassa, God of the Sea can make creatures unblockable as well as you get the scry 1 each upkeep.
Bident of Thassa, Coastal Piracy, Reconnaissance Mission all help with draw perhaps in the absence of the commanders, as there are a lot of low cost flying creatures that should be able to get damage in on at least one opponent most games.
