Hmm... The Ambitious Card routine itself is non-gimmicked but you can get some awesome finishes for it that are gimmicked.
If you're referring to the Ambitious Card Routine where the card keeps coming to the top, that is not gimmickified.
However if you're referring to Masuda's Ambelitious Card/Deck where the card is inserted into the deck and the deck vanishes leaving only the selected card then I believe that effect is gimmicked, yes.
Hope that's helped.
