Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can Special Summon this card (from your hand) by Tributing 1 "Blackwing" monster. If Summoned this way, this card is treated as a Tuner monster. Once per turn: You can target 1 Synchro Monster you control, and declare a Level from 1 to 8; it becomes that Level until the end of this turn.
