I'm not sure if I did or not, as I often open them right away.
There's a rumor that 3pm Central is a good time to open, but it's likely an urban myth.

so did you try opening super cubes in the time period?

Notice how the def down occurs after the 4x attacks. I think it did not use to be that way. Ofc, I'm in part speculating as she was nerfed sometime last year without knowing what the specifics were/are. For instance, a year ago many would put 2 to 3 Asters in their defense as the meta - at least that meta is over for the most part as the gameplay wasn't unique and "needed" a nerf so to speak.

8:04 to 8:07 am central standard.
yeah. it looks / feels kinda programmed, maybe? i think that's 10?
(i stil lhave remainiing 8 from my 10 pack purchase)
Pretty much feeders. Im not going green aster, but i do need Asters.
I did not know there was nerf to Aster's Skill 3.
so it's not 16x anymore?

That's weird to get the streak of 4*s like that. It's almost like they programmed a certain number of 4 stars for your given account? Sounds like you got your quota albeit a round about way.
Also, do you happen to know what time of day you did this?
I saw a Green Aster in there. Aster has slowly been getting weaker as newer units come out and there was a nerf on the A3 awhile ago. Even so, she's a decent unit. Also, go enough Annette's to make her decent. So, you might be set without Lotus.
