Well, I've noticed something else, although it's probably intentional.
There are plenty of times where you'll play cards and get no animations. That's fine. However, there are also cards that are completely inconsistent. Sometimes they play an animation, and sometimes they don't. I couldn't figure it out at first.
On looking at the game's files, the reason for this inconsistency is that there exist .mp4 files which are acting as placeholders. They don't have any actual runtime when I examine them with VLC. I suspect these empty files are there to make sure that the game's code has something to reference without returning an error instead, but since they have no content, there's nothing to play when they proc in the code.
If this annoys anyone else like it did me, I have a solution of sorts. I've taken to deleting these empty .mp4s in my local copy of the game and replacing them with copies of the .mp4 files that actually do work, so that there's always an animation of some sort playing with those cards. You might see a particular animation more often than others, but it's better than none playing at all. The only downside is that there are a LOT of these empty .mp4 files.
EDIT: Okay, I swear, last thing. The "Breed Me Daddy" card doesn't seem to work.
