Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
During the Main Phase: Banish 1 "Dual Avatar" Spell/Trap from your GY, except "Dual Avatar Compact"; this card's effect becomes that Spell/Trap's effect when that card is activated. You can only activate 1 "Dual Avatar Compact" per turn.
