Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Cannot be Normal Summoned/Set. Must first be Special Summoned (from your hand) while you control no monsters. When this card is Special Summoned from the hand: You can Special Summon 2 "Vague Shadow Tokens" (Winged Beast-Type/DARK/Level 1/ATK 0/DEF 0), but they cannot be Tributed or be used as Synchro Material. You can banish this card and 1 or more face-up non-Tuners you control, then target 1 "Blackwing" Synchro Monster in your Graveyard whose Level equals the total Levels the banished monsters had on the field; Special Summon it, and if you do, it is treated as a Tuner.
