Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
All Level/Rank/Link 2 monsters currently on the field gain 1400 ATK/DEF until the end of this turn. During your Main Phase: You can banish this card from your GY, then target 1 Level/Rank/Link 2 monster you control; it gains 1400 ATK until the end of your opponent's turn. You can only use 1 "Spright Gamma Burst" effect per turn, and only once that turn.
