MAGIC: THE GATHERING
Enchantment - Aura
Enchanted creature has "At the beginning of your upkeep, sacrifice this creature."
When enchanted creature is put into a graveyard, its controller chooses target creature one of his or her opponents controls. Return Necrotic Plague from its owner's graveyard to the battlefield attached to that creature.
|Until end of turn, creatures you control gain trample and get +X/+X where X is the greatest power among creatures you control. (If a creature you control would assign enough damage to its blockers to destroy them, you may have it assign the rest of its damage to defending player or planeswalker.)|
