Yes - You need another 800-1200 seal scrolls for another super rare.
No - Stop drawing from there, there's 50% chance you'll get Ay duplicate.

You can instead start saving for GNW treasure, 50% chance to get either Kurama Naruto or Madara out of 800-1200 seal scrolls.

Or you can do Lightning Treasure first 210 scrolls for brother Ay 3rd then run Earth main Samui/ Ay 3rd/ Ay 4th snipe blitz.

thx alot for the quick reply bro!!!

Just so you know, Ay is much more powerful than Sasuke. So unless you wanted Sasuke for flavor reasons, be happy about your draw :)

Dupes would only occur after you've pulled both super rares from the treasure. So you can pull if you still would like Sasuke, but again that is 800-1000 seals of ninjas that you may no longer use. Also, drawing Ay is a pretty decent pull. In the future he pretty much stomps in all 1v1 scenarios with skillbreaks.. Sasuke on the other hand dominates GNW as his skilbreaks make his mystery not only crossfield but he gets stronger everytime a unit dies. Things to consider. As of now, both of them are subpar, Ay does have the upper hand if you have samui though.

The best plan of action at this point in the game is to get Kurama or Madara as Azrielle stated. You'll get more use out of them.

If you don't have Roshi, I would strongly recommend picking him up as well.

Han and Ay the 3rd are optional. I personally do use Han more than Ay though for pvp (Sage world, matsuri, space time), but the vast majority just plug him into a ranked lineup

This man said "unluckily" got Ay. Unless you got shisui, itachi susanoo and need sasuke then im UPSET

people told you is 800-1000 more, but this is how kage treasure worked before 3.0.

before 3.0 you used to get one super rare at 900 and the second super rare at 1800, but this is no more how it works.

Now once you reach the 1000th draw you unlock the superares as common rares and every time you pull an rng lucky draw or you hit the counter you can get them as any other common rares. Very likely you'll get the other superare within your next 4 rare draws (so within 280 more pulls). Beware that is not sure, just very likely. Is sure only if you don't pull early rng lucky pulls and if you pulled before all the other common rares.
