The Secret Door

When The Secret Door enters the battlefield look at
the top ten cards of your library. Add any of those
that are treasures to your hand. Put the rest on the
bottom of your library in any order.
{t}: Create a treasure token. Activate only if a
creature you control delt combat damage to a player
this turn.

Stand by the grey stone when the thrush knocks, and
the setting sun with the last light of Durin's Day will
shine upon the key-hole.
