Well I think jellydonut is just trying to have a little fun with what is an awful set overall for Legacy. I think it's too bad that cards like this aren't good. But attrition via synergy just isn't a winning strategy at the moment with the notable exception, as always, of lands.
That being said ... It's also really interesting with Hide/Seek. You Seek their Angler, gain 7, put it in their GY and kill their Delver.
