that "sideboard" is a maybeboard just saying..plus Immortal Servitude might be good and no one plays white without Path to Exile or something like that..for lands you might wanna go with Windbrisk Heights and maybe Emeria, The Sky Ruin for late game

Thanks spilacus !!

Disciple of Bolas is one of my favourite cards, very usefull to draw massive amounts of cards and gain life at the same time. Combine it with Undying Evil or your Kitchen Finks and you got yourself a nice combo!

Martyr of Sands can be very useful in this deck.You can also use Spectral Procession for create creatures and gain life.Another good cards is Honor of the Pure

Thanks afterlife , and some black that could fit into this deck??

For black you can use Lingering Souls for the flashback cost.

Maybe Inquisition of Kozilek or Thoughtseize in order to remove some useful cards in the opponent's hand or some removal spells like Smother .

Ghostly Prison and/or Blind Obedience could ward off an Aggro assault.

-4x Gods Willing , +4x Spectral Procession . You get 3 1/1 fliers, which combos really well with your soul sisters. Also, Auriok Champion and Ajani's Pridemate are pretty good in this type of deck as well.

Thank you aeonstoremyliver and Saljen :)
