Dilux

I just got the Squirtle from Byxbysion and im wondering who i should replace it with Pokemon and moves: Nidoking: Thrash, Sludge wave, Earth power, Shadow claw Aurorus: Ancient power, Freeze-dry, Discharge, Avalanche Gothitelle: Future sight, Feint attack, Psychic, Dark pulse Blaziken: Double kick, Blaze kick, Flame charge, Bulk up Tropius: Leaf tornado, Body slam, Air slash, Dragon dance Ninjask: Fury cutter, Swords dance, Night slash, Slash

Ok so basically i killed the golett and im asking if there is any way of making it appear again since i kinda used a doll on it. and i cant go back because my last save was like 5 hours ago
