“Hey guys, whatcha doin’?” The official Pokemon Card blog has revealed Sudowoodo from Rage of the Broken Sky. Thanks goes to Jake C. and Michael S. for the translation!
[F][C] Let’s Imitate: If your opponent used a Pokemon’s attack during his or her last turn, use that attack as this attack.
Weakness: Water (x2)
A lone Sudowoodo hanging out with a bunch of Trevenant is probably a reference to the Trevenant Horde Battles on Route 20 in Pokemon X and Y.
