Competitive Intrigue

Counter target non-Dimir spell or destroy target non-Dimir creature (a Dimir creature is blue and black or has a Dimir watermark).
Surveil X, where X is the countered spell's or destroyed creature's converted mana cost. (Look at the top X cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.)
Any good agent knows the best work is done for you.
