A Beautiful Discovery

Artifice (This spell costs {1} less to cast for each card
in your hand. If you don't pay {1} for this spells mana
cost, you may discard a card then draw a card.)
Sacrifice X artifacts. For each artifact sacrificed
this way, reveal the top card of your library. If
it's a non-artifact card, you may play it without
paying its mana cost, if its an artifact, put it into
your graveyard.
