Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can send 1 Spellcaster monster from your hand or face-up field to the GY; Special Summon this card from your hand. You can declare 1 Attribute; this card becomes that Attribute until the end of this turn. You can banish this card from your GY, then target 1 "Magistus" monster you control; equip it with 1 "Magistus" monster from your GY, except a Level 4 monster. You can only use each effect of "Crowley, the Magistus of Grimoires" once per turn.
