2. Mega Evolution is Essential: Placing Mega Gengar or Mega Sceptile in your party will boost the power of all trainers' Ghost or Grass-type moves. A Mega Evolution is a key factor in significantly increasing your raid success rate.
3. Prioritize High CP Pokémon: Even a top-ranked Pokémon can struggle if its CP is low. It's better to fill your party with 6 Pokémon with a CP of 2500 or higher to ensure a stable damage output.
