This deck efficiently summons from Sacred Phoenix of Nephthys, while taking advantage of his effect to destroy all spell traps by destroying him. Duel, standby! is used to give you enough cards for the many combos of this deck.
Sacred Phoenix of Nephthys is practically immune to destruction by card effects, as he revives himself during your next standby phase when destroyed this way. In addition he wipes all spell/trap cards on the field when revived with his own effect, allowing you to safely attack your opponent. It also doesn't matter who destroys him, so you can take advantage of his effect by destroying him with your own effects.
When fire king avatar yaksha is destroyed and sent to the graveyard, he allows you to destroy a monster in your hand on field. Destroy Sacred Phoenix of Nephthys in your hand to special summon him your next standby phase.
Sphere Kuriboh can be activated from the hand therefore it would be a better choice for this deck than to add protection spell and traps which would most likely be destroyed by your Sacred Phoenix of Nephthys.
Super Rush Headlong protects your monster from attacks by monsters of an attribute you declare. Helpful since most archtypes revolve around a single attribute, forcing your opponent to end the battle phase.
