Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
1 "Nordic Alfar" Tuner + 2+ non-Tuner monsters Once per turn, when your opponent activates a Spell/Trap Card during your Battle Phase (Quick Effect): You can negate the activation, and if you do, destroy it. Once per turn, during the End Phase, if this face-up card you controlled was destroyed by your opponent's card and sent to your GY this turn: You can banish 1 "Nordic Alfar" Tuner from your GY; Special Summon this card. When Summoned this way: You can target 1 Trap in your GY; add that target to your hand.
