Lavinia, Azorius Renegade [Ravnica Remastered]

Each opponent can’t cast noncreature spells with mana value greater than the number of lands that player controls.
Whenever an opponent casts a spell, if no mana was spent to cast it, counter that spell. I told Jace that Ravnica would fall apart if he didn’t take his responsibilities seriously. I didn’t want to be right.
