The Paladin

When the only other players are The King, their
teammates and your teammates, reveal The
Paladin and you all win the game. When
there is no King, you lose the game.
Turn The Paladin face up: As long as The Paladin
is face up, whenever you or the current king
would take damage, lose life, or gain life, the
other player also takes that damage, loses that life
or gains that life. Whenever you or the King adds
mana to their mana pool, the other player also
adds that mana.
