Lord Tywin, Warden of the West

When you sacrifice a creature, you may pay {b}. If you do, Create a Treasure token.

"It fell to Tywin to restore House Lannister to its proper place. Just as it fell to him to rule this realm, when he was no more than twenty. He
bore that heavy burden for twenty years and all
it earned him was a mad king's envy."
- Kevan Lannister
