Set Wild Tornado then use Storm to destroy it. This will trigger the effect of Wild Tornado to destroy a face up card while using Storm to destroy opponent's spell/trap, allowing you a chance to OTK your opponent.
Steal enemy monster
Use the second effect of Enemy Controller to gain control of an enemy monster to open for a direct attack. Then before the end phase use Dimension Gate to remove the monster from play.
When your opponent tries to attack you directly or when Dimension Gate is destroyed, special summon the monster removed from play with Dimension Gate's effect. With this combo, you gain permanent control of the monster.
The current meta uses a lot of Relinquished after the event of Pegasus, this card can easily counter them. Another use of this card is depleting your hand by removing spell card to activate it, great to boosts your Flash Assailant ATK and DEF.
it doesnt work as well because WT can be destroyed by storm and use its second effect on your turn
Personally I don't think this deck is meta anymore. First of all, this deck was created by Dkayed during the WC final qualifiers to counter meta decks of that moment (Weevil, Harpie, etc), Dkayed explained the mentioned above in a video. Now we have two new card boxes and structure decks so the meta has changed to swarming decks, which are much faster than this deck. Even I doubt if Dkayed itself would use this deck in this actual form, probably he would modify it before using it to counter the counter meta.
