Okay, let's try again rephrased.
Does 614.17d apply to Grafdigger's Cage? Or not because it says “creature card”?

614.17d Some “can’t” effects may modify how a permanent enters the battlefield or whether it can enter the battlefield. Such effects may come from the permanent itself if they affect only that permanent (as opposed to a general subset of permanents that includes it). They may also come from other sources. To determine which “can’t” effects apply, check the characteristics of the permanent as it would exist on the battlefield, taking into account replacement effects that have already modified how it enters the battlefield (see rule 616.1), continuous effects from the permanent’s own static abilities that would apply to it once it’s on the battlefield, and continuous effects that already exist and would apply to the permanent.

A while ago the Gatherer rulings seemed to say yes: http://webcache.googleusercontent.com/search?q=cache:GLVjHa2LOigJ:gatherer.wizards.com/Pages/Card/Details.aspx%3Fprinted%3Dtrue%26multiverseid%3D426046+&cd=1&hl=en&ct=clnk&gl=nl

But the current Gatherer page for Grafdigger's Cage doesn't have those rulings: http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=426046

Still, it does not have the ruling anymore that says no: https://magic.wizards.com/en/articles/archive/feature/modern-masters-2017-edition-release-notes-2017-03-03
