Saheeli's Directive

Improvise (Each artifact you tap after you're done activating mana abilities pays for {1}.) Reveal the top X cards of your library. You may put any number of artifact cards with mana value X or less from among them onto the battlefield. Then put all cards revealed this way that weren't put onto the battlefield into

your graveyard.
