Stuffy Doll and Pariah's Shield is amazing, you could proprebly just straight up win the game with that combo.
Since we are already using white because of
the wanderer,
Pariah can also be used in stead of
Pariah's Shield. It's easier to get rid of the aura, but there is a significant difference in the mana cost.
Besides that,
Sower of Discord wouldn't work, because he causes life loss in stead of damage.
