Flourishing Defenses

Enchantment, 4G (5)
Whenever a -1/-1 counter is placed on a creature, you may put a 1/1 green Elf Warrior creature token onto the battlefield.¹
Many horrors take the bait of brave elf volunteers walking alone, only to fall to the blades of rescuers lurking nearby.
Illus. Dan Scott

Gatherer Card Rulings [Nov 2009]

• 5/1/2008: This ability triggers both when a -1/-1 counter is put on a creature on the battlefield and when a creature enters the battlefield with a -1/-1 counter on it. This includes when a creature returns to the battlefield as a result of persist.
• 5/1/2008: This ability triggers once for each -1/-1 counter. For example, if Leech Bonder (a creature that enters the battlefield with two -1/-1 counters on it) entered the battlefield, Flourishing Defenses's ability would trigger twice.
