Quicksilver Obelisk

Imprint — When Quicksilver Obelisk enters the battlefield, search your library for an artifact
card and exile it, then shuffle.
{t}, Discard one or more cards with total mana
value equal to or greater than the exiled card's
mana value: This permanent becomes a copy of
the exiled card until your next end step.
Monuments in Esper are built not in honor of what
was, but what shall be.
