A "creature card" is a Creature card or Artifact Creature card. [D'Angelo 1999/05/01] Older cards of type Summon are also Creature cards.
Removes the creature from the game no matter how it leaves play, including Unsummoning or being killed. [D'Angelo 1995/11/15]
If it is removed from the game by Safe Haven, then this effect will not do anything additional. Each player has only one "out of the game" zone, so this effect will not cause the Safe Haven to lose track of the creature. [WotC Rules Team 1996/10/03]
The remove from the game is a replacement effect. [D'Angelo 2000/03/09]
