As i've said previously, cards with no atr are effectively dead !
The cc's modify them in such a way that they cannot be ressurected without some specialist glitching. Basically, they redirect the card into an infinite loop straight out of reset. The card is not set up at this point and can neither receive or transmit messages. It just sits there in its loop !
As an added safeguard to stop you applying just one glitch, they have also applied the same patch to the main message interpreter loop rendering the card incapable of actually processing messages of any nature.
