You have six attempts to draw three different seals, that’s barely any RNG at all, it’s practically guaranteed.
First card can be any of the three seals.
Your second card has a 2/3 chance of being different, so two card draws should be all you need to get a different 2nd seal.
Last is 1/3 chance of being a different seal, and you have three draws left to get it.
That’s six card draws, and you have six draws between Divinations.
Not even accounting for Redraws, of which you can have up to 8 between Divinations if you hold charges, or 6 if not.
I don't think it'll be that braindead though.
You still need to figure out where a card needs to go, and whether or not you need that seal or minor arcana it.
Pretty much the same as deciding where Spear/Arrow go, and to minor arcana Bole. RR Spire/Ewer is replaced by Divination.
You lose the utility of Ewer, but that's about it.
