Lady Catelyn Stark

Devoted Mother—Creatures you control get +1/+1
and creatures you don't control get -1/-1.
Resourceful—Whenever a creature you control dies,
you may pay {1} to create a clue token.
"All his life Tyrion had prided himself on his
cunning, the only gift the gods had seen fit to give
him, yet this seven-times-damned she-wolf Catelyn
Stark had outwitted him at every turn."
