While we're piling on with reasons why this card would be fake, I'm pretty sure that they've had a policy not to print lands in Standard sets that don't tap for mana unconditionally, unless it has some sort of fetch to the battlefield effect.
I'm really not sure about your sideboard choices. As somebody else pointed out to me a few weeks ago, Ghostly Flicker in Tron makes Spreading Seas very impractical as an answer to Tron. Maybe something like Thermokarst if you want to have land destruction in your sideboard? Otherwise, something like Nihil Spellbomb (even without the card draw) or Tormod's Crypt can be far more crippling against most flavours of Tron than land destruction. I'd also consider running something other than Gut Shot against Elves. Maybe Echoing Truth. You'll probably want some number of copies of Gleeful Sabotage against Affinity and Astrolabe decks. This also gives you another option against Bogles. You might even want to run Serene Heart in stead of Reverent Silence.
Second, a few months ago we ran a video primer on this exact strategy that might give you some more ideas. The only major change (the video was filmed before Modern Horizons came out) would be to switch out the playset of Sultai Emissary for Putrid Goblin. Persist is a far less clunky way to keep bodies on the board than Manifest. Another card I'd run at least two or three copies of somewhere in your 75 is Pestilence. There is quite a bit of aggro in the meta right now, and something like Elves can easily swarm the board while they use Wellwisher and Weather the Storm to negate your burn strategy. This can be supplemented by swapping your Maggot Carriers for cards like Festering Mummy and Shambling Goblin, with Carrion Feeder as your main sac outlet to let you snipe your opponent's creatures. There's some very interesting choices in your list, I really like Trespasser's Curse.
One thing that comes to mind immediately is running a number of copies of Nameless Inversion in your removal suite, since it can be recurred with Ghoulcaller's Chant.
Mystic Sanctuary gives pauper decks another option for Ghostly Flicker loops besides Wall of Omens/Archaeomancer, and a less vulnerable one at that. The condition of having at least three islands makes it less viable for something like Tron, but still very useful.
Wonder what the other three Quest artifacts will turn out to be. One of them must be a Holy Grail variant. What else is there in Arthurian lore that would qualify?
There's an thirteenth century middle-Dutch Arthurian novel about Sir Gawain being sent on a quest to retrieve a floating chess board. It's a very obscure text, but I'd love to see it included.
As much as I understand the need for new art, the Fifth Edition art always struck me as one of the most expressive pieces of Magic art ever printed. I would have loved to see that used again, especially considering how well that particular art fits the theme of the set.
I'm working on a more budget-oriented version of Marisi (no card other than Marisi more that $1 TCGplayer mid), and I had considered Horsemanship, until I realised that no Horsemanship creature in the appropriate colours falls outside my budget limitations. But on that note, what the hell happened to the price of Yellow Scarves Cavalry? I'm used to seeing prices spike over hype for a new commander card that suddenly makes them relevant, like Yuriko causing a spike in the price of a lot of ninjas and Arcades doing the same for certain walls, but going from $2 to $82 at its peak is insane. Is this all from Marisi? Or is this some sort of buyout? I know PK3 commons are in very short supply, but still.
Honestly, looking at these lists, compared to what it was a few months ago, I'd rather have the current meta than what we had pre-Daze/Gush ban, with Tireless Tribe and Ux control decks dominating the meta. What's especially salient is that we now have several different aggro decks that are uniquely positioned to prey on Astrolabe decks that don't hit critical mass until the fourth or fifth turn. I'd say it looks like a very healthy balance of control and aggro, with some combo sprinkled in.
As for your fear of Weather the Storm and Reaping the Graves maindeck, only three decks run Weather the Storm as a sideboard card, and only one of those runs more than one copy. And there's a lone copy of Reaping the Graves floating around in the sideboard of the Astro-Mardu list.
Overall I don't believe that Arcum's Astrolabe is a problem. Sure, it's a popular card, but a card needs to do more than popular to justify being banned. There's plenty of strong independent decklists that don't need no Astrolabe. Plus, it seems like every week there's at least one or two rogue decklists being piloted to 5-0 finishes, which means that the meta has plenty of room for niche decks that are run well. Last week we had Sultai Defender Combo. This week we had Mono-Green Infect and Mono-Black Aggro. I think looking at the meta purely in terms of Astrolabe vs. no Astrolabe does a huge disservice to the diversity of the meta right now.
One card I think might be worth considering that I missed in this article is Gallant Cavalry. Two 2/2 bodies with Vigilance for 3W seems like a good deal.

Eye Collector - B
Creature - Faerie
Flying
When ~ deals combat damage to a player, each player puts the top card of their library into their graveyard.
1/1
And I can definitely see this being slotted into MBC/zombies as a one/two off:
Witch's Cottage
Land - Swamp
Tap, add B.
~ enters the battlefield tapped unless you control three or more other Swamps.
When ~ enters the battlefield untapped, you may put target creature card from your graveyard on top of your library.
Again, about half the decks (nine out of twenty-one) run Astrolabe. However, we are once again looking at a very diverse meta:
Elves: 2
Jeskai Ephemerate: 2
Tireless Tribe: 2
Astrolabe Affinity: 1
Astro-Mardu: 1
Bogles: 1
Burn: 1
Classic Affinity: 1
Dinrova Tron: 1
Familiars: 1
Izzet Delver: 1
Mardu Pestilence: 1
Mono-Black Aggro: 1
Mono-Black Midrange: 1
Mono-Green Infect: 1
Mono-Green Stompy: 1
Mono-Red Stompy: 1
Mono-White Heroic: 1
