Vanishing 3
(This permanent enters the battlefield with three time counter(s) on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
Imprint — When Idris, Soul of the TARDIS enters the battlefield, exile another artifact you control until Idris leaves the battlefield.
Idris has all activated and triggered abilities of the exiled card and gets +X/+X, where X is the exiled card's mana value.
