Dora

When Dora enters the battlefield, it explores,
then explores again. (Reveal the top card
of your library. Put that card into your hand
if it's a land. Otherwise, put a +1/+1 counter
on this creature, then put the card back or
put it into your graveyard.)
One of the five artificial intelligent drones created
by a long-dead North Quart scientist whose own
genius had sent him mad.
