Archivist's Familiar

When Archivist's Familiar enters the battlefield
put a +1/+1 counter on each other Archivist you control.

When you catalog Archivist's Familiar search
your library for an Archivist card, reveal that
card, put it into your hand, then shuffle.

Guff's assistants still linger about the library.
