生灵宿敌

Text:

你坟墓场中每有一张生物牌，生灵宿敌便减少来施放。
：蛮化5。你坟墓场中每有一张生物牌，此异能便减少来起动。（如果此生物未蛮化，则在其上放置五个+1/+1指示物且它蛮化。）

Rulings:

• 9/15/2013 Neither the cost-reducing ability of Nemesis of Mortals nor the condition of its monstrosity ability can reduce the colored mana requirement of those costs.
• 9/15/2013 Once you declare you’re casting Nemesis of Mortals or activating its ability, it’s too late for players to try to change the number of creature cards in your graveyard to affect the cost of doing so.
• 9/15/2013 Once a creature becomes monstrous, it can’t become monstrous again. If the creature is already monstrous when the monstrosity ability resolves, nothing happens.
• 9/15/2013 Monstrous isn’t an ability that a creature has. It’s just something true about that creature. If the creature stops being a creature or loses its abilities, it will continue to be monstrous.
• 9/15/2013 An ability that triggers when a creature becomes monstrous won’t trigger if that creature isn’t on the battlefield when its monstrosity ability resolves.
