Terror in the shadows rewards

Does anyone know what the exclusive reward cards were for the Terrors events?

And are they available in the vault yet? I see three or four cards that are marked event exclusive, but I am not sure if that is past or future events. I think I have played against some of the though, leading me to think they were past.

I am specifically interested in the first three terror events, Since I missed those.

Thanks to everyone for your help.
