Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target 1 "Dual Avatar" monster you control; destroy it, and if you do, Special Summon 1 "Dual Avatar" monster from your Deck or Extra Deck, whose original Level is 1 higher or 1 lower than that monster had on the field. During your Main Phase, except the turn this card was sent to the GY: You can banish this card from your GY, then target 1 "Dual Avatar" monster in your GY; add it to your hand. You can only use each effect of "Dual Avatar Ascendance" once per turn.
