I find it odd that this isn't getting more attention, especially since some are saying this deck is supposed to be really good.
I am not really sure about that. I might just be an absolute noob, but the deck construction is pretty anti-synergetic. Sometimes I fan out openers like James stated above with Orchard, Tropical, Fastbond, Gush, Gush, Force, Thoughtseize. Looks okay, but does nothing. I don't really want to rely on a land-topdeck (since I'm also the type of guy who would topdeck a second Orchard and then go on tilt).
Then there are openers where I think "broken, 1st Turn Jace with Backup" - but that Orchard will then make a token that will erode my Jace. In theory, I have to bounce the token immediately and never use Orchard again to keep my Jace on the board.
Nobrainers like 1st Turn Mox Orchard Oath with backup are pretty obvious, but I can't deal with openers like stated above. I am also not sure when to bounce everything my opponent has and just beatdown and when to combo him out. Especially because Tyrant's trigger is not a may-effect and bouncing stuff is mandatory when you play a spell. And you basically can't go infinite with double Tyrant without bouncing the second Tyrant etc.
Huh? Of course you can.
I have to say that I have no practical experience with this deck so far, I have just thrown it together and goldfished it a bit to see how it may behave and so far I am no really convinced. It simply plays a lot of cards that are dead when they are redundant. The same is true for the regular Oath (Elephant-/Iona-Oath).
This is not a deck to goldfish. If you don't have any experience with Gush decks, then this deck is probably not for you. You need to understand how to maximize the advantages derived from Gush, such as when to play Gush and how to sequence Gush with other spells. Gush decks in this day and age don't goldfish. They are highly situational in play. You need to know when to Gush to create opportune mana and card advantages.
Furthermore, the interface of Tyrant, Gush and Jace, particularly with Flash of Insight, creates an another layer of decision-making complexity. Flash of Insight alone requires extreme care, knowing how much to remove in your graveyard, and a clear sense of what you are trying to tutor up. For example, in many situations, the only card you want to tutor up is Mox Sapphire to go infinite with Jace.
