Your best bet is to set up the Episode card like usual:
<def tag="card" for="Episode">
..etc..
</def>
Then PlaylistEpisode (which I'm assuming has_one or belongs_to Episode)
<def tag="card" for="PlaylistEpisode">
<card:episode merge>
...do some stuff here...
</card>
</def>
The only messy thing is that you'll have to (I think) refer to the
PlaylistEpisode in the second part as this_parent.
If I've mis-guessed, and PlaylistEpisode is a subclass of Episode,
then you'll want to do this:
<def tag="card" for="PlaylistEpisode">
<card for-type="Episode">
... do stuff here if PlaylistEpisode is a subclass of Episode
</card>
</def>
The cookbook section on polymorphic tags is pretty handy here too.
