Only a minor adjustment to the watchlist, but worth noting anyway.
Because of the continued dominance of André's Dirty Kitty deck, we decided to put Empty the Warrens back on the watchlist. The card has been on and off the watchlist before, but before Zendikar the deck proved to be very beatable with some dedicated sideboard hate. Goblin Bushwhacker changed all that however, as the deck can now play the full set of Fecundities, and is far more lethal with 2/1 hasty goblins.
So far no one else has picked up the deck, and we think sideboards are not optimally equipped to beat the deck. If, however, more people start playing Dirty Kitty, and their overall performance takes on Affinity-era proportions (losses to only mirror matches and dedicated maindeck hate decks) despite proper sideboarding, we will have to take more drastic measures to ensure a healthy environment.
