Verzauberung
Immer wenn du eine oder mehrere -1/-1-Marken auf eine Kreatur legst, erzeuge entsprechend viele 1/1 schwarze Insekt-Kreaturenspielsteine.
If an effect has you put more -1/-1 counters on a creature than it has toughness, you’ll put all of those counters on it and create that many Insects, even if that makes its toughness a negative number.
If a creature with wither or infect deals damage to a creature, the controller of the creature with wither or infect puts that many -1/-1 counters on the second creature.
