Changes

First, start with a [[Heavy Storm]] or [[Giant Trunade]] (if they have set spells/traps already), to prevent your opponent from interrupting your lock and fouling your plans. Then set [[Anti-Spell Fragrance]] and summon [[Dark Simorgh]] (either regular tributing, or with its effect from the hand or graveyard, or using [[Swallow's Nest]] to swap out a different level 7 winged beast to summon it from the deck). For the most part you want to keep it in defense position so they can't suicide monsters that might destroy it by effect. During your opponent's standby phase, activate [[Anti-Spell Fragrance]] and the lockdown is complete. You opponent will be incapable of setting monsters or spells and traps, and they won't be able to activate their spells at all without setting them first. Being unable to set monsters to defend, their lifepoints will be at your mercy, and their only escape from this lock would be defeating Dark Simorgh in battle, or using monster effects to destroy your locking cards, things you will prevent with cards such as [[My Body as a Shield]] and [[Divine Wrath]]. Both of which can easily be dealt with by your own spells and traps (which are not locked down at all).
