As long as Aggron ex is your Active Pokémon, your opponent's Basic Pokémon can't attack or use any Poké-Powers or Poké-Bodies.
During your next turn, Aggron ex can't use Mega Burn.
Choose 2 of your opponent's Pokémon. This attack does 30 damage to each of them. (Don't apply Weakness and Resistance for Benched Pokémon.)
When Pokémon-ex has been Knocked Out, your opponent takes 2 Prize cards.
