Assuming you mean
this (CAsercan3/Infinnacage's EoSD phantasm, which is more of a humor thing), and I am kinda aware of what IN Phantasm you're talking about (Assuming you mean the Flandre one, which is NOT made by danmaq I think) which I both cannot find the video of and actually asked Naut about a long time ago, but the message he sent (and the DL link in the message) is gone now apparently.
