I agree, plus this card would only work well if the game is Hidden mode and if the opponent is not playing blindly (i.e. what would be done with -tower decks or +tower decks) and if it was the last card played for a couple of hours (i.e. someone logs off Marcomage, and then comes back to continue playing). So one would keep it in their hand, thus occupying a precious space until the right moment to play it or it would be quite useless to play. Although it's quite interesting as it can counter Reveal cards and reset tokens, I think the people who take it in their decks will be discarding it more often than playing it.

last card played/discarded is no longer considered "last card" (or a little bit shorter "last card is no longer considered last card")
I believe he doesn't want just that effect, he also wants the cards played and discarded to not be visible as usual
