Asimov's Lair

When an artifact creature you control dies, place counters on this card equal to its power on the
field.
{p/b}{p/b}{t}, Remove any number of counters from
this card. Place that many +1/+1 counters on
target creature.
{4}{p/b}{p/b}{t}, Remove ten counters from this card.
Search your library for an artifact creature card,
reveal it, add it to your hand, then shuffle your
deck.
