Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target 1 "Therion" monster in your GY; Special Summon it, then you can equip 1 "Therion" monster from your hand or GY to it. During the Main Phase: You can banish this card from your GY, then target 2 "Therion" monsters (1 on your field and 1 in your GY); equip that monster from your GY to the other monster you control. You can only use 1 "Therion Stand Up!" effect per turn, and only once that turn.
