The Sheaf of Papers

{t}: Name a permanent in your library. You may search for that card and put it into play. Put 2 stun counters on this card. (If a permanent with a stun counter would become untapped, remove one from it instead.) This effect cannot be countered.

advance-warning system or whether SCP-001 itself is
to be regarded as the creator of the items requiring special containment remains to be seen.
