5 rulings from Wizards of the Coast
- 22 September 2011If the ability resolves, but the damage is prevented or redirected, the controller of the targeted creature will draw X cards, regardless of how much damage was dealt or what the damage was ultimately dealt to.
- 22 September 2011If the damage is lethal, the cards are drawn before the creature is destroyed (the next time state-based actions are checked).
- 22 September 2011If the creature is an illegal target when Nin's ability tries to resolve, it won't resolve and none of its effects will happen. No player will draw cards.
- 22 September 2011The effect is not optional. The creature's controller can't choose to draw fewer than X cards.
- 22 September 2011You may choose a value for X that's greater than the creature's toughness. Its controller will draw that many cards.
