The responsed you gave are basically correct. Here are a few thoughts. My
initials are la so when you make you statements, remove my initials and
then add yours. This will avoid a lot of typing. It also makes it possible
to keep track of different ideas.
Your pack is a little difficult to compare with the dole which is why I
had a more horizontal arrangement, but if you prefer the vertical that is
readable as well.
The problem is whith your dole. Nine of Hearts and Five of Clubs are your
first two cards. The Nine of Hearts goes in the first hand. The Five of
Clubs in that mix of cards would be the first card dealt into the second
hand. Your are trying to simulate a real deal of the cards so you continue
third card to third hand and so forth. By showing two deals, you establish
that the cards have really been shuffled and then are dealt correctly. You
have made a deal as it should be. The real problem is that it doesn't match
this shuffle.

Personally, I find the embargo requirement daunting. I also had some
trouble with the way you had phrased the task -- I sent an email about
some of those issues, and received no response.
That said, with a concrete example of what you are looking for, I can
provide workalikes and comments.

(I like the rdm version better but you might not accept it.)

Note that your original instructions were unclear about the role of
the left argument for mixla. It's clear now that you do not use the
left argument. That said, neither of my above definitions will ignore
the left argument. For that, use:
mixlardm=: ]{~ [:?~ [:# ]
mixla=: ]{~"1 [:?~ _1{ [:$ ]
However, in my opinion, this kind of a "you must handle a left
argument by ignoring it" thing smells bad. It complicates that code
and thus makes future revisions more difficult and makes understanding
the code harder.
dolela=: _13 ]\ mixla
dolelardm=: _13 |:\ mixlardm
dolela packla
...
dolelardm packlardm
...
Or, if you want extra shuffles (though it's not clear if they do
anything meaningful):
dolelardm mixlardm^:2 packlardm
(results omitted here for brevity).
