This card works well with Geartown because if you use Heavy Storm to destroy both this card and Geartown, you get to activate both of their effects.
This card works very well against the effect of Judgment Dragon to destroy him by his own effect.
If you have Decoy Dragon on the field and a Level 7 or higher Dragon Type monster in your hand and also a Raigeki Break face down, then you can activate it discard your Dragon Type as the cost for Raigeki Break then target your face down Wild Tornado and destroy any card on the field. You now have "fuel" for Decoy Dragons effect and you destroyed one card on the field.
Don't use this with "Magical Hats", as it must be set when destroyed to gain its effect. this card will be flipped face up during the damage step if it is destroyed by battle.
It still triggers if it is destroyed by magical Hats effect, or another card effect while set by magical hats.
This card's first effect cannot target field spells, even if they are face up. The field spell zone is not considered part of the Spell/trap zone.
This card combos well with Gigantes' effect to destroy spells and traps, since it activates in substep 6. Bujins cannot negate it by that point, and a card like Evilswarm Thunderbird cannot dodge out of it.
