Destroys 1 Spell/Trap card your opponent controls.
It is a Quick-Play spell, can be activated during your Opponent’s Main or Battle Phase.
Destroys 1 of your own Spell/Trap card as a cost.
The difference between this card and Parallel Twister is that, Parallel Twister may be able to destroy any card your opponent controls, but it is not a Quick-Play spell so the usage is limited to only your Main Phase. They both have pros and cons for different situations.
Very important to take note, both targeted Spell/Trap card from your field and your opponent’s Field can be chained in response to Double Cyclone’s activation, if they are able to be used during that moment.
This card destroys Spell/Cards but does not negate their effects should the cards were activated in response to this card.
It can be a good idea to use characters that has Field Spell skills, so that you may start with a Field Spell on your field, that can be used as a cost should the situation requires it.
Destroy own cards
Wild Tornado can destroy 1 face-up monster when it is being destroyed and sent to the Graveyard. You can equip Big Bang Shot to your opponent’s monster, and use Double Cyclone to destroy Big Bang Shot, and destroy 1 targeted opponent’s Spell/Trap, also banishing the monster equipped with your Big Bang Shot at the same time.
Just a small note: you can chain this card with every spell/trap card you activate, being normal trap like wall of disruption or quick play spells like econ, cosmic cyclone, super rush, or why not, another double cyclone. If you do that you won't waste your backrow to destroy opponent's backrow. So this card becomes a SR dust tornado, destroying enemy's backrow for free
