Llanowar Empath

The smoothing function for a card-draw engine, doing two jobs that usually live on separate cards. Scry 2 fixes your next two draws; the reveal-and-grab clause turns your library's top into a guaranteed creature when it cooperates. The sequencing is the design payoff: you scry first, so you can stack a creature onto the top before the reveal resolves, converting the scry into a deliberate tutor rather than a coin flip. That interaction rewards knowing your own deck's draw order, and it lifts this above the flat dig of an Elvish Visionary or the bottom-of-the-curve Wood Elves: green has a long line of creatures that find more creatures, and this one adds selection on top of the find. A 2/2 here is deliberately modest, priced so an engine creature does not also become a beater; the entry trigger is the whole reason for the slot. The catch sits in that reveal clause, which only hands you a creature: whiff on a noncreature card after the scry and you have spent four mana on two cards' worth of bottom-of-library smoothing and a small Elf with a spent ability. Build a creature-dense list and the whiff rate falls toward nothing, which is precisely the deck this was made for.
