Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You Normal Summon/Set WIND monsters with 1 less Tribute than ordinarily required. (You can only apply this effect once per Summon/Set.) This card is treated as a Normal Monster while in your hand. If this card is Tribute Summoned by Tributing only WIND monsters: target up to 2 cards your opponent controls; return them to the hand. * The above text is unofficial and describes the card's functionality in the OCG.
