After seeing Force of Negation and Nimble Mongoose I could not resist, as these cards overpower this deck so much (I dare say Nimble Mongoose is the best creature for this deck since Goyf).
I'm gonna try 2 variants:
"Classic" RUG Delver
and another which I feel may be even better, Wrenn and Six is retardedly good.
Very excited for Horizons to come out
