Call the Mountain Chocobo (Final Fantasy 131) - Common Magic: The Gathering Card

Search your library for a Mountain card, reveal it, put it into your hand, then shuffle. Create a 2/2 green Bird creature token with "Whenever a land you control enters, this token gets +1/+0 until end of turn."
Flashback (You may cast this card from your graveyard for its flashback cost. Then exile it.)
