Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target 1 monster on the field; banish 1 monster with 1500 ATK/2100 DEF from your hand, your GY, or face-up on either field, and if you do, the targeted monster gains 1500 ATK. If this card is banished and you control a "Kashtira" monster: You can target 1 Effect Monster your opponent controls; negate its effects until the end of this turn. You can only use each effect of "Kashtira Overlap" once per turn.
