As Hex Maniac has now been banned from the Expanded Format, there is to be no more Hex Chaining your opponent's Sudowoodo and Egg Filling your bench, which leads me back to a metagame that dominated last year's Dallas regionals of Zoroark/Alolan Muk. This list plays a heavier count of Alolan Muk...
Great ideas @Merovingian, goodbye 4 Float Stone and hello 4 Warp Energy! My only concern is that Float Stone can be Trainers' Mailed, whereas Warp cannot. As @DKQuagmire already said, ditto probably wouldn't help this deck as much as we'd like it to, but it was still a good idea nonetheless. I...
