Japan’s Pokemon Twitter has revealed Ho-Oh EX from Rage of the Broken Sky. Thanks goes to Bangiras and Jake C. for the translation!
Ho-Oh-EX – Colorless – HP180
Ability: Cleansing Flame
Once during your turn (before your attack), if this Pokemon has any basic [R] Energy attached to it, you may heal 50 HP from this Pokemon.
[G][W][L] Elemental Feather: 130 damage. Choose 1 of your opponent’s Benched Pokemon. This attack does 30 damage to it. (Don’t apply Weakness and Resistance for Benched Pokemon.)
When a Pokemon-EX has been Knocked Out, your opponent takes 2 Prize cards.
Weakness: Water (x2)
Resistance: Fighting (-20)
So you need four different Energy on Ho-Oh to take full advantage of it. At least collectors will like it. :)
