Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Activate this card by banishing 2 monsters you control, then target 1 face-up monster your opponent controls; Special Summon this card in Attack Position as an Effect Monster (Spellcaster-Type/DARK/Level 4/ATK ?/DEF ?) with ATK and DEF equal to that face-up monster's ATK. (This card is also still a Trap Card.) If this monster is Summoned this way: Inflict damage to your opponent equal to this card's ATK.
