Hey, thanks! The main purpose of Stroke of Genius is as a secondary win condition if we somehow can't go for the Ugin win. The reason why I chose Stroke of Genius over Blue Sun's Zenith is that it's much easier to cast (X2U instead of XUUU) outside of that win condition. While that's not something we normally want to do, Stroke makes it much easier for us to pull off if we really have to. The reason why Stroke works as a backup win condition is because we can bring it back with Timetwister, Time Spiral, and Snapcaster Mage after we've gone infinite on Mana and Draw with Teferi + Chain Veil.

I see no reason not to be running Scroll Rack. It's not listed in your notable exclusions. Your even running the fetches to take advantage of the shuffle. As well as other shuffle effects.

Also might as well run Wasteland as you are running Strip Mine and I'm assuming you would only strip non-basics most of the time anyways.

Heavenly Axe: I have my own chain veil teferi, and although I obviously haven't made this one, I thought it might be useful to here my reasons why. For Wasteland, the reason I don't run it isn't lack of power or anything, it's taking away a colored mana slot in the mana base. Teferi is incredibly strong once it starts going, but you need plenty of sources of colored mana. If you've noticed, there's not many artifacts in the deck that produce colored mana, so to combo off with the Chain Veil you usually need about two basic lands, and you want to maximize your capacity of keepable hands.As for Scroll Rack, I originally had it in my version, but had to cut it, not because it's not great, I love the interaction with fetches, but because it happened to be the least playable card in my deck. If something else gets banned, or gets cut due to a rules change, I would include it at once, but for me it doesn't fit in the deck.

Re HeavenlyAxe: While Scroll Rack looks like a fine card on paper, there are several reasons why it doesn't fit into Teferi. You did identify that the deck does indeed have enough shuffle effects to justify its inclusion in that regard, but there's much more to that card.

1. It's slow: Scroll Rack takes uses up three Mana at a point in the game where we usually want to develop our board. Due to several of our Mana-positive rocks being non-untapping (Mana Vault, Grim Monolith, Basalt Monolith), we don't actually have that much Mana we can comfortably use on things like Scroll Rack. And if you're looking to only use it when the game goes longer, then that's honestly not a good way to look at it. You want to minimise the amount of cards that are going to be useless in half (or more) of your games.

2. The deck already has plenty of draw and card selection that's significantly more powerful than Scroll Rack.

3. It doesn't actually generate card advantage: Scroll Rack doesn't draw us cards, and it also doesn't really provide card selection outside of being used with a shuffle effect.

All in all, Scroll Rack is the kinda card you'd run when there's nothing better to run for card selection in your colours (think like Mono White with Scroll Rack + Land Tax). Teferi has a lot of better options, so we don't need a card like that. For Wasteland, I'll point you towards Wasadia123's comment, since they were spot on.

Have you considered As Foretold here maybe? Or do you think that maybe it will be too slow for this?

Anyways looks like a good deck you have here for sure, +1.

Thanks a lot! And yeah, I thought about it for a bit, and probably would've played it if the card made it possible to play my Sorceries or Mana rocks on other people's turns. Sadly, it doesn't, and it takes several turns cycles to really start being useful, so it'd be another one of those cards that aren't useful when we're going for a fast combo win.

Awesome list!

Just some questions: What's your thoughts on using Turnabout to Maximize high tide. Also with the amount of artifacts mana you have, how useful has high tide been?

Think of High Tide in this deck more as Dark Ritual than as High Tide in something like JVP. We're not trying to do big HT combo turns with it, we can use it as a ritual effect to get a bit more mana or as an enabler for the Chain Veil combo, which it has been doing a very good job of. That's why cards like Turnabout or Candelabra of Tawnos are not good in Teferi.
