I'm not sure if this guy is good enough for my cube, but if they don't give me another homerun, I'm gonna test him out. Dimir is the one of 2 guilds I don't really have a hybrid for (
Nightveil Specter acts more like a gold card with that cost), so I'm probably moving this to gold and try the Agent.
I mean, it works as ambush removal, it sets up a good draw and/or fuels your graveyard, and a control deck can just hold back mana and cast him eot when they had no need to spend their sorces to counter, bounce or destroy something. Not super powerful, but flexibility could make up for it.
Also, I am ALL OVER that art/flavour. This is everything I missed from most Dimir cards in Ravnica 2.
