I am working on a dark elder swarm deck. A link to my deck is here: http://www.conquestdb.com/en/public/deck/9e0eee5eff0151c8-swarm-de-deck

You can read all of the details of my deck above (how it works e.t.c.).

I currently am in the 30s with cards and still need a few more to have a deck of 50. The problem is that I don't know any more effective cards that would work with my deck.

Could someone please have a look and provide me ideas?

Thank You!
