I've made a meme deck years ago utilizing Balustrade Spy and Undercity Informer to win via literally having a landless deck and milling the entire library for a Dread Return win.
It was of course pretty reliant on having alternative ways to produce non-land mana and this made the deck very inconsistent. It was more for the theory-crafting and not really serious at all.
With the advent of Zendikar Risings transform lands we now have a way to pack in a lot of lands, but they won't be recognized by cards as lands while in the library due to the rules.
Once you mill your whole library you can use a number of ways to potentially win.
Dread Return can be used to put Thassa's Oracle into play.
Goblin Charbelcher is another card that combos with having "no lands" as you can deal damage equal to the number of cards left in your deck. You also get to stack your library anyway you want to as you get to put them back into your library in the order you want.
It makes sense to add other ways to mill your library so we have Cephalid Illusionist that will mill cards when targeted and Lightning Greaves or Nomads en-Kor can target indefinitely.
Hermit Druid with all non-basics will do it.
Even though this is a meme deck, it's full of one or two card combos, so is actually pretty scary to play against, threatening to win with even the slightest opportunity.
Right so the downside of these lands is that you only get to play 6 of each color and 25 of them come into play tapped. It's a pretty slow and inconsistent land base for fixing.
There are some cards for helping this with Realmwright, Joiner Adept, Prismatic Omen, Dryad of the Ilysian Grove, Chromatic Lantern.
Amulet of Vigor also means that those lands come into play untapped.
Root Maze will put you on equal footing with lands with your opponents.
So do the 30 modal spell/lands have any synergy as spells in the deck? Well it is a bit of a ragtag mix of spells. But at the end-of-the-day the deck is 99 spells, so given this you will have more cards to cast potentially than opponents.
The deck can leverage off this by getting a Omniscience into play off probably Academy Rector, so that you can freely cast these spell, no matter how minor an impact for value.
Dream Halls can be used in the same way, and with realistically 30 more colored cards than opponents you will have more cards to match up than most.
Trade Routes can return your lands if you want to later on cast them for the spell portion.
I also wanted to use Bolas's Citadel as often a sticking point can be the one land per turn limit preventing a big turn. With all spells you can keep going for as much life as you have.
