Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can Special Summon this card (from your hand) by returning 1 "U.A." monster you control to the hand, except "U.A. Midfielder". You can only Special Summon "U.A. Midfielder" once per turn this way. During either player's turn: You can target 1 other "U.A." monster you control; return that face-up monster to the hand, then Special Summon 1 "U.A." monster from your hand with a different name from that monster. You can only use this effect of "U.A. Midfielder" once per turn.
