This effect prevents cards stacked on top from being trashed by <De-Digivolve> or other effects, and cards stacked on the bottom can't be trashed by effects such as those that trash digivolution cards.

After this effect activates, the current timing makes a transition to the end of attack timing. For example, if this effect activates during the attack declaration timing, it will make a transition to the end of attack timing. A transition to the counter timing or block timing won't occur, and the attack won't succeed.
