Zuran Orb was so good at stalling out games that it was restricted in large part to make sure tournament matches finished
As previously mentioned, the Enchanted Rare cards are only found at the rate of 1 in every 3 booster boxes, or thereabouts, so pulling one is an especially lucky find
Whenever a land card is put into a graveyard from anywhere, you may pay
Lillie's Clefairy EX is part of this expansion, identified by collector number 173/159
These effects are combined with a number of powerful synergies that trigger when you sacrifice a creature or can help generate value when combined with your sacrifice effects including Elas (drain your opponents) as well as Phyrexian Missionary (can return a creature from graveyard to your hand), Phyrexian Warhorse (creatures creature tokens as a target to sacrifice), Braid's Frightful Return (returns a creature to your hand from the graveyard), as well as Writhing Necromass which is a strong body and can be cast way ahead of curve as you sacrifice creatures
Its interesting to note that if you want to make the card get more incidental value, some versions of cards from the Portal sets have reminder text, like the Portal 2 version of Ravenous Rats (although I dont think that has a home, even in pauper cubes)
