Enduring Renewal

Enchantment, 2WW (4)
Play with your hand revealed.
If you would draw a card, reveal the top card of your library instead. If it's a creature card, put it into your graveyard. Otherwise, draw a card.
Whenever a creature is put into your graveyard from the battlefield, return it to your hand.¹
Illus. Harold McNeill

Gatherer Card Rulings [Nov 2009]

• 10/4/2004: Enduring Renewal only affects creature cards that are "drawn". It doesn't affect cards that are put into your hand from your library, or from anywhere else.
• 10/4/2004: If the creature is only a creature due to an effect, it still goes to your hand. This includes any way to animate a card.
• 10/4/2004: Token creatures cease to exist if they leave the battlefield, so this effect will not let you get them in your hand.
• 7/15/2006: The last ability is now a triggered ability, not a replacement effect.  That means your opponent has the opportunity to remove the card from your graveyard while the triggered ability is still on the stack.
• 9/25/2006: Unless something weird happens, the card you draw as a result of the second ability will be the card you revealed.
• 9/25/2006: If, after the last ability triggers, the creature card is removed from your graveyard in response, it won't be returned to your hand.
• 4/1/2008: A "creature card" is any card with the type Creature, even if it has other types such as Artifact, Enchantment, or Land. Older cards of type Summon are also Creature cards.
