Winterfell

{t}:Add {r}, {g}, or {s}{s} to your mana pool.
House Stark—Whenever a Stark enters the battlefield under your control you may search your library for a dire wolf card. Reveal it and put it into
your hand. If you do not, create two 2/2 North
Bannermen creature tokens.
"The Lord of Winterfell would always be a Stark."
—Tyrion Lannister
