The Gearbook

{t}: Add {c}. Put a gear counter on The Gearbook.
{t}: Choose an artifact card in your graveyard. If
its mana value is less than or equal to the amount
of gear counters on The Gearbook, return it to
the battlefield. Otherwise, return it to your hand.
Activate only as a sorcery.
Remove a gear counter from The Gearbook: it
gains indestructible until end of turn.
