Can I use feat cards on Sentinels or just the battlefield conditions on them?

Just a couple of threads down we have this thread.

You can use feats on Sentinels unless the errata specifically says a particular feat does not work (Lazarus Pit, Shellhead)

Also note that feats are deactivated when the Sentinel uses Multi-Attack.

Oh, and BFCs aren't technically played on a figure, they're just kinda there.
