(Part 2 of 3)

At level 70, AST learns Divination and gains the trait Crown Seals.
With the trait, Lord and Lady of Crowns now gives you a Lord or Lady seal which is displayed on the updated job gauge. Additionally, when you have one seal, Minor Arcana draws the Crown card corresponding to the seal you don’t have. This ensures that each pair of Minor Arcana uses gives you one Lord and Lady each.

After getting both Crown seals, Draw turns into Divination. Divination consumes both Crown seals and is largely the same—AoE damage buff—but also draws a card for you to play so your rotation stays aligned to a 2-minute window.

The AST starts encounters with all astrosigns and seals so they can start off with Divination.
Minor Arcana and Divination share a recast timer with Draw so they stay aligned to the 15-second increments.

The two minute rotation now looks like this:
0-15s Divination > Combust > Play > Malefic > Malefic >
15-30s Draw > Malefic > Play > Malefic > Malefic >
30-45s Draw > Combust > Play > Malefic > Malefic >
45-60s Minor Arcana > Malefic > Crown Play > Malefic > Malefic >
60-75s Draw > Combust > Play > Malefic > Malefic >
75-90s Draw > Malefic > Play > Malefic > Malefic >
90-105s Draw > Combust > Play > Malefic > Malefic >
105-120s Minor Arcana > Malefic > Crown Play > Malefic > Malefic > (Repeat)

A downside to this setup is that your rotation drifts by 15 seconds if you give a card to an incorrect target once. I recommend bringing back Sleeve Draw to help mitigate this.
Sleeve Draw and the trait Lesser Fortune are learned somewhere between level 50 and 70. Sleeve Draw has a recast time of 2 minutes.
The trait Lesser Fortune gives you the buff Second Chance for 15 seconds when you play a card and don’t get an astrosign. Sleeve Draw can only be used when you have the buff Second Chance. Sleeve Draw draws a card and replaces the Second Chance buff with Lesser Fortune buff. Lesser Fortune halves the damage buff of the next card that’s played.

Even though Sleeve Draw can help fix your rotation, it gives access to another card which means people will intentionally misplay a card to be able to use it. Additionally, it’s an action you get while leveling so should be beneficial to use and not solely just for fixing a mistake. Going for Sleeve Draw comes at the cost of casting one less Malefic to use Play and introduces a little complexity to the rotation so the DPS gain should be carefully managed. I feel halving the damage buff is a good compromise but that might be too harsh.

Sleeve Draw in an opener would look something like this:
0-15s Draw > Combust > Play incorrectly [Sleeve Draw oGCD] > Malefic > Play >
