Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Special Summon this card as an Effect Monster (Beast/EARTH/Level 2/ATK 0/DEF 2000). (This card is also still a Trap.) If this card is in the Monster Zone (Quick Effect): You can declare 1 Type and 1 Attribute, then target 1 face-up monster on the field; it becomes that Type and Attribute, until the end of this turn. You can only use this effect of "Mimesis Elephant" once per turn.
