Pendulum Summon this card using "D/D/D Doom King Armageddon" and "D/D Proud Ogre" as the Pendulum Scales, and then use this card's effect to destroy two of your Spell and Trap Cards, giving this card the capability to attack three times this turn. Use the Pendulum Effects of "Armageddon" and "Proud Ogre" to increase this card's ATK to 4100 for massive damage.
You can also Pendulum Summon at least 1 other Level 7 monster alongside this card to increase your capability of ending the duel in an OTK. In the event that you fail to OTK your opponent, overlay this card with that other Level 7 monster to Xyz Summon "Mecha Phantom Beast Dracossack" or "Red-Eyes Flare Metal Dragon" to continue putting pressure on your opponent.
Use this card's effect to destroy your "Dark Contract" cards after having used their effects, in order to avoid the damage penalty they would inflict during your Standby Phase.
