Send this card to the Graveyard with "Dragon Shrine". Send another monster, preferably a LIGHT monster (usually "Eclipse Wyvern"), in order to have a LIGHT and DARK monster in order to summon a Chaos monster.
This card can easily clear the field with this card, a level 8 normal or Gemini monster, and "Supervise": Send both of them to the Graveyard (with "Trade-In", "Foolish Burial" etc), summon this card (with "Swing of Memories", "Silent Doom", etc) and equip with "Supervise" to gain its effect, then activate its effect to destroy all Spells and Traps cards on the field. Special Summon the other monster with the effect of "Supervise" to Xyz Summon "Thunder End Dragon" and detach one Xyz Material to destroy all other monsters for a direct attack.
Prior to detaching an Xyz Material for "Thunder End Dragon" and entering the Battle Phase, Special Summon "Light Pulsar Dragon" and then remove an Xyz Material. Light Pulsar's effect will activate, allowing you to OTK by summoning "Red-Eyes Darkness Metal Dragon" and summoning another monster for a total damage of over 8000.
Send this card to the Graveyard (with "Featherizer", "Trade-In", "Foolish Burial" etc), use the effect of "Blazewing Butterfly" and Special Summon this card from your Graveyard.
Send an activated "Castle of Dragon Souls" to the Graveyard to activate this card's effect and Special Summon a banished monster.
If this card is in the Graveyard, by using only "Birthright" or "Soul Resurrection" to Special Summon this card and using a Normal Summon, this card can destroy all Spells and Trap Cards on the field. Keep in mind, though, that this card will be destroyed as well.
Use this card in a Ninja deck that uses "Ninjitsu Art of Super-Transformation". If you manage to Gemini Summon this card, you can send one of your Ninjitsu Art cards to the graveyard for this card's effect. Take note that using its effect after being Special Summoned this way will inevitably cause it to get banished, since either way "Ninjitsu Art of Super-Transformation" will leave the field.
To avoid your cards being destroyed, have "White Dragon Ninja" on the field before you activate the effect.
You can use "Mausoleum of the Emperor" to summon this card, then after activating it's effect you can use "Mausoleum of the Emperor" to destroy all other Spell and Traps.
Utilizing Continuous Spell or Trap Cards such as "Birthright" or "Call Of The Haunted" will be of good use in increasing the chance of using "Darkstorm Dragon"'s effect.
