1 Tuner + 1+ non-Tuner monsters
When your opponent activates a monster effect (Quick Effect): You can banish it. If this attacking card destroys an Effect Monster by battle and sends it to the GY: This card gains ATK equal to the destroyed monster's original ATK, also it can make a second attack on a monster during this Battle Phase. You can only use each effect of "Draco Berserker of the Tenyi" once per turn.
