The official Pokemon Card blog has revealed Ferroseed from Rage of the Broken Sky. Thanks goes to Bangiras for the translation!
[M][C] Harden: During your opponent’s next turn, if an attack would do 60 or less damage to this Pokemon, prevent that damage.
Weakness: Fire (x2)
Resistance: Psychic (-20)
Fun fact: Ferroseed is pronounced “fur-AW-seed.” Not “fair-o-seed.” Ferrothorn is pronounced “fur-AW-thorn.” Both rhyme with “hurrah,” as in “furrah-seed” and “furrah-thorn.”
