Dozy Squirrel

Dream (When you cast this spell, you may have it
have a dream, if you do, it enters the battlefield tapped
it doesn't untap until you have taken damage.)
When Dozy Squirrel enters the battlefield, if it
had a dream, search your library for a basic land
card and put it into your hand. Then shuffle
your library.
