Landstill is slow as hell and will need to eventually counter 2 out of 3 cards that you draw. I see most game ones against Landstill going like this: Get in early creature beats. They deal with your critters while you toss burn at their heads. Eventually they hit a critical point in their life total where they need to decide if they want to counter Bolts while risking a PoP to the dome. Game one should be very much in your favor.

However, game two can provide you with some headaches since the have effective hate cards. Depending on the colors being run, Landstill can have accesss to Chill and/or CoP: Red. Be sure to board in your Krosan Grips. I can imagine that a UBW build running discard and CoP: Reds could have solid game two against Goyf Sligh.
