Corruption Multi Cultural

[Gaurwaith]

Lately i watched a Game on Gemp where someone used corruption Deck around multi cultural which looked quite good. Sth i have never seen before and doesn't seem to be a standard deck. Since i just watched 2 sites i don´t know all the Cards used. The main cards where:

Gollum Stinker
Witch King Lord of the Nazgul
It wants to be found
Grima Wormtongue
Sarumans Power
Easterling Lieutenant

Does anyone every builded a Deck like this and can help me building it?
