Hi,

The Schema (Any Format) reader can be used to read feature schemas from a dataset.
The reader creates features each of which contains a schema information including feature class name ("fme_feature_type_name" attribute). You can then determine if required feature class exists.

@takashi I am pretty new to FME and am wondering how exactly I can check if a feature class exists? I was able to successfully load in the schema of the GDB and I see the attribute mentioned, but what transformer would help me best here? How can simply check if it exists?

Another option is to use a Creator, AttributeManager, and PythonCaller, as shown in the following screenshot.
I have attached the same workspace for reference.

@courtney_m thank you, but can explain a little about what it is you put together? Why do I need to create a new fc?
