Quote from user-100005099 »Are you guys thinking that it's possible to utilize Marit Lage's Slumber in EI deck? Running a few Flooded Strands and new Prismatic Vistas with a lot of snow-covered basics supported by Scrying Sheets would make one scry a lot. Having double white mana on t2 could be tough, but we can replace Runed Halo with On Thin Ice. Also note that if your Marit Lage is somehow dealt with you can return Slumber on top with Hall of Heliod's Generosity and sacrifice it once more.
Quote from user_938036 »So they recently add this feature to the game where you can use your creatures to attack another player's planeswalkers. This new feature will allow you to interact with planeswalkers in an obvious and simple way with cards you should already be playing.
On a serious note, they did alter a number of uncommons, rares and even a few commons to specifically answer planeswalkers. There is a lot of paper in the format to answer the rocks. Planeswalkers are showing up more than ever because there are more than ever but they are far from dominating.
