I will give a try at this too, since looking at the videos I think I understand what you are looking for.
But first, if you can´t do english, try to write a standard German(Deutsch?), for example, in perfect grammar and no slang words, that way, google translator will do a better job in case a dumb Brazilian user like myself try to help out.

First, in your loop, you need SHOWSCREEN at the end within the loop, so all fine so far.
Now for your rotating cards to fall rotating and land in a normal straight position, I would do as follow:
.Create a state condition for the cards, like CARDSTATE
.If CARDSTATE=0 then it falls down rotating
.If at the bottom, then CARDSTATE=1
.If CARDSTATE=1 then just keep it rotating untill it is shown on the rest position, straight position, at which point CARDSTATE=2
.If CARDSTATE=2 then it is just there showing it self still and not rotating
So here, not all transformations on the card happens all the time within the loop but just those that the CARDSTATE dictates.
Keep in mind you have to keep drawing your card through every state otherwise SHOWSCREEN will delete the last one displayed.
If this idea rings a bell, I can write some pseudo code to help further.
Of course this is just one approach to the problem.
Cheers.
