It is rather bizarre that it's not a creature as the card's sole focus and name is on Shahrazad (or Sheherazade), a character from the 1001 Arabian Nights story, but that's not even the least of why this card is so iconic
Festering Gulch The difference between Festering Gulch and Jungle Hollow is marginal, but they're both ever-so-slightly better than a basic tapland like Foul Orchard
Why should a good thing end after flipping a card
Whenever this creature deals damage, you gain that much life
Say you have two cards in hand: a Tarmogoyf and a Remand
Also, positive side note: The draft didn't feel like on rails, cause I had the option to go Orzhov lifegain pretty much the whole time, than just left the white stuff in my sideboard, because the monoblack payoffs seemed stronger and were more plenty.
