4/4
With all due respect, but in some of the newer fluff Elesh Norn is described as having an obsession with religion, and she believes every religion has angels. Thus, she has angels.
But I agree with the infect bit. Also, it wouldn't work against a flying deck, as it destroys all non-flyers.
Anyhow...
