Houndoom-EX (xy8-21) is a Basic Fire-type Pokémon-EX from the BREAKthrough set and is printed as a Rare Holo EX. Its first attack, Melting Horn, mills the top two cards of your opponent's deck while its second attack, Grand Flame, deals 50 damage and reattaches a Fire Energy from your discard to a Benched Pokémon. The card carries the Pokémon-EX rule causing your opponent to take two Prize cards if it is Knocked Out.
