Looking to build around the synergy between Diregraf Colossus + Binding Mummy/Wayward Servant

What I've got so far:

Anguished Unmaking
Binding Mummy
Cemetery Recruitment
Declaration in Stone
Diregraf Colossus
Dread Wanderer
Festering Mummy
Gideon of the Trials
Graf Harvest
Liliana, Death's Majesty
Liliana's Mastery
Lord of the Accursed
Plague Belcher
Reprisal
Time to Reflect
Wayward Servant
Westvale Abbey
Isolated Chapel
Cradle of the Accursed
Plains
Swamp

Dark Salvation seem like an obvious add, but I haven't pulled it yet.
