Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is Normal or Special Summoned: You can target 1 Level 8 or lower monster you control; its name becomes "Fleur Synchron", also it is treated as a Tuner, until the End Phase. You can Tribute this card; add 1 Equip Spell from your Deck to your hand. You can only use each effect of "Noble Knight's Spearholder" once per turn.
