Shigure Sohma

Whenever an opponent casts a spell, counter it
unless that opponent pays life equal to that
spell's converted mana cost.
Sohma Curse (When Shigure Sohma blocks or
becomes blocked, exile it face down. It becomes a
1/1 Black Hound creature with Lifelink until the
end of your next turn.)
"He is like a tide... A tide that carries you away when
you get too close to it."
