Cresselia Weakness Raid. Shiny cresselia is available in pokémon go. This guide uses level 30 counters with no aditional boosts or dodging use to score their effectiveness, so it may seem.

Cresselia is a gen iv legendary, part of a lunar duo with darkrai (who, curiously, is a mythical pokemon). Cresselia is a psychic type pokémon, which makes it weak against bug, ghost and dark moves.
