Hansel two of your statements in your post contradict one another. I susoect that English is not you first language? Which is cool.
Just trying to clarify which it was.
Here you have said that that those (including Seeker Iris) were never obtainable.
But then here you have said that they could be found only in the old purge, but are no longer available.
Could you please do me a solid and clarify @Hansel?
