*Minor Arcana
Lord: oGCD damage, adds 10 seconds to combust if active
Lady: oGCD heal, increased any card effects by 5 seconds

New Ability
Magic Hour: An oGCD that can only be used out of combat. Learned at level 50. Fills all missing arcanas in your stack so you can start a raid with Horoscope.
Will remove any active royal roads, stored cards, and minor arcanas. It's a clean slate.

Celestial Opposition: Revert it's effect, stun and increases any Astro support effects by some 10 seconds (does not work with Horoscope for balance's sake?)

Sleeve Draw: Reworked, redraw the last arcana added to the stack. Does not affect your stack. 90 second cooldown.
On a personal note, I like the theme of this move as you using Geomancy to cheat fate a little bit in your favor. Seems like cool flavoring.

-Upon reaching level 50 you learn Horoscope and can use it whenever you have all 6 arcanas in your stack (so you need to play any stored cards).
-Cards are still on a 30 second cooldown, meaning horoscope is essentially a 3-minute cooldown
-Since you know that within a 3 minute interval you will have drawn each arcana, you can plan accordingly.
This will probbaly lead to a bunch of spread sheets and charts to maximize your card effects no matter the order, I welcome this personally.
-Lady is basically the old time dilation now, Celestial Intersection is kind of the new Lady anyway
-Lord having extended combust is just to go along with the themeing of time extension alongside Lady

'Balance-fishing' as it was before is now about getting the arrow and spear out in a way that works for your party. If you have 3 ranged dps and 1 melee in your comp, it will be better to power up the spear with another arcana instead of expand it. For people that are all about pushing dps, it's up to you to adjust and play with spear and arrow card based on the order you draw cards and your team comp.

For progging, you can focus more on heal boosting and defense boosting cards. I really like the idea of super powering a balance card and then using aspected benefic for a super shield or regen (now combine this with Neutral sect).

Using Discard/Horoscope will not eliminate any royal road effects or minor arcanas you have active, so you can bring that into your next phase. Using enhanced Spires on magic dps jobs might lead to some DPS gains for Red Mage and Black Mage?

So there you have it, by making the cards predictable as you draw from your deck you can normalize your buff rotation slightly. In theory, you're truly encouraged to play with all your cards because you know that the cards you care about will come back in 6 draws or less. The stack as a visual indicator helps keep track of what you've used. The devs will never read this, there are probably tons of problems and holes, I don't care. I just want to throw my hat in the ring and keep the astro conversation going. Maybe one day I'll like Astro again. Now go ahead and rip this apart.
