Pokemon Go Holidays 2021 Part 1 guide: Postcard Book, new costumes & wild encounters

Complete guide to Pokemon Go Holidays 2021 Part 1 with advanced strategies and optimization tips

Event Overview and Strategic Timing

Pokemon Go’s festive Holidays 2021 celebration kicks off with an immersive Part 1 event featuring exclusive content and seasonal surprises that transform your winter gameplay experience.

The two-part Holidays 2021 extravaganza launches with Christmas-themed content including the debut of Bergmite, special costumed Pokemon appearances, and the innovative Postcard Book feature for enhanced social gameplay.

Niantic has crafted this seasonal celebration to maximize player engagement during the holiday period, strategically splitting content to maintain excitement throughout December. The debut of Ice-type Bergmite provides collectors with new Pokemon to pursue, while returning holiday costumes offer nostalgic value for veteran trainers.

Our comprehensive guide covers advanced strategies for every aspect of Part 1, from optimizing your wild Pokemon encounters to mastering the competitive Holiday Cup format and leveraging new social features effectively.

Part 1 of the Pokemon Go Holidays 2021 event commences on Thursday, December 16, 2021, at 10am and concludes on Thursday, December 23, 2021, at 10am local time, giving players exactly one week to complete all exclusive content.

Strategic planning is crucial since Part 2 immediately follows from December 23 through December 31, requiring resource management across both events. Advanced players should prioritize Part 1 exclusives before the second phase begins.

Wild Encounter Optimization Strategies

The wild encounter pool during Part 1 features carefully curated seasonal Pokemon with varying rarity levels that require different hunting approaches for optimal results.

Available wild encounters include:

  • Alolan Sandshrew – rare spawn requiring specific biome conditions
  • Pikachu (Holiday Hat) – common but time-limited costumed variant
  • Advanced Hunting Technique: Use Daily Adventure Incense during event hours to increase rare spawn chances. Alolan Sandshrew appears more frequently near parks and water features, while Holiday Hat Pikachu clusters around PokéStops with holiday decorations.

    Common Mistake Avoidance: Don’t waste Poké Balls on common spawns when hunting rares. Prioritize Pinap Berry usage on costumed Pikachu for extra candy, saving Golden Razz Berries for potential shiny encounters or high-IV Alolan Sandshrew.

    Field Research Task Mastery

    Event-exclusive Field Research tasks provide guaranteed encounters with festive Pokemon, offering reliable acquisition methods beyond random wild spawns.

    Field Research reward encounters include:

  • Pikachu (Holiday Hat) – perfect for collectors seeking costumed variants
  • Task Prioritization Strategy: Focus on tasks that reward Holiday Hat Pikachu first, as these provide exclusive content unavailable after the event. Complete easier tasks daily while saving more time-consuming ones for weekend play sessions.

    Advanced Player Tip: Stack completed research encounters to use with Star Pieces during double candy hours. This maximizes candy gains for Pokemon you’re planning to evolve or power up for the Holiday Cup competition.

    Raid Boss Tactical Analysis

    The raid boss rotation during Part 1 features seasonal and Ice-type Pokemon that align with the holiday theme, requiring specific counter strategies for efficient farming.

    Counter Strategy Development: Ice-type raid bosses are weak to Fighting, Fire, Rock, and Steel-type moves. Prepare teams featuring Machamp, Lucario, Reshiram, and Metagross for optimal performance against the event’s featured bosses.

    Raid Hour Optimization: Coordinate with local communities for Wednesday raid hours during the event period. Use remote raid passes strategically to join raids in different time zones, extending your daily raid opportunities.

    Bonus Exploitation Guide

    Multiple event bonuses provide significant advantages for resource accumulation and gameplay efficiency during the Holidays 2021 celebration.

    Available bonuses include:

  • Open up to 45 Gifts per day, and hold up to 40 Gifts in your Item Bag. – Perfect for stocking up on Poké Balls and potions
  • Mega Abomasnow will get a CP boost during event hours. – Enhanced performance in raids and gym battles
  • Team GO Rocket Grunts will have more Water- and Ice-type Pokémon. – Easier shadow Pokemon farming
  • New festive avatar items will be available from the in-game shop. – Limited-time cosmetic collectibles
  • Get holiday-themed stickers by spinning PokéStops and opening Gifts. – Additional collection element
  • Gift Management Strategy: Send gifts immediately after opening to maintain continuous gift flow. Prioritize friends who regularly send gifts back to maximize item acquisition from the increased daily limit.

    Mega Evolution Optimization: Use Mega Abomasnow during raid hours and against Team GO Rocket leaders for maximum benefit. The CP boost makes it exceptionally effective against Dragon, Flying, Ground, and Grass-type opponents.

    Holiday Cup Competitive Mastery

    The Holiday Cup returns to the Go Battle League on December 16, 2021, at 1pm PST, offering a specialized format that challenges trainers to build creative teams within strict constraints.

    This festive competition restricts participants to Normal, Grass, Electric, Ice, Flying, and Ghost-type Pokémon only, with a strict 1500 CP limit that emphasizes strategic team building over raw power.

    Meta Analysis: The type restrictions create a unique meta where Ice-types counter Flying and Grass, while Electric-types threaten Water and Flying. Ghost-types provide coverage against Psychic and other Ghosts, creating complex type relationships.

    Team Composition Strategy: Build balanced teams covering multiple type weaknesses. Include at least one safe switch option and one closer. Popular choices include Alolan Marowak, Lanturn, Froslass, and Vigoroth for their typing and move coverage.

    Common Competitive Mistakes: Avoid overloading on one type, neglecting proper move coverage, or using Pokemon without second charge moves. Test your team in practice battles before entering ranked matches.

    Postcard Book Advanced Features

    The new Postcard Book feature debuting on December 16, 2021, transforms gift interactions from temporary exchanges into permanent collectibles with strategic value.

    This innovative system allows trainers to save postcards received from Gifts as cherished mementos of their global friendships and travel experiences.

    Collection Strategy: Prioritize saving postcards from distant friends for potential future trading value. Rare PokéStop locations and event-specific postcards may become highly sought after by collectors.

    Friendship Optimization: Use the Postcard Book to track your interactions with international friends. The visual record helps maintain engagement with remote friends who provide long-distance trade opportunities and raid support.

    Access the Postcard Book through your Item Bag or Trainer Profile once the feature becomes active, organizing your collection by location, friend, or date received for easy navigation.
