Pokemon Go Evolving Stars Collection Challenges: Eevee, Trade, Unova & Sinnoh

Master Pokemon Go’s Evolving Stars event with expert strategies for all four Collection Challenges and rewards

Evolving Stars Event Overview

The Evolving Stars celebration has begun in Pokemon Go, bringing four distinct evolution-themed Collection Challenges that dedicated trainers won’t want to miss. This limited-time event provides an excellent opportunity to expand your Pokedex while earning valuable evolution items.

Pokemon Go’s Evolving Stars event features four specialized Collection Challenges: Eevee evolutions, trade-based evolutions, Unova region creatures, and Sinnoh region species.

Beyond the Collection Challenges, trainers can engage in multiple activities including the Cosmic Companion Special Research storyline, evolving Cosmog into Cosmoem for the first time, and challenging powerful new Raid Bosses that have appeared during the event.

The four Collection Challenges each focus on different evolution mechanics, providing a comprehensive tour of Pokemon transformation methods. Successfully completing all challenges requires strategic planning and efficient resource management.

Our detailed guide covers every Pokemon needed for all four challenges, including specific evolution requirements and proven strategies for accumulating the essential candy needed for transformations.

Eevee Collection Challenge Guide

To conquer the Eevee Collection Challenge, you’ll need to obtain multiple Eevee evolutions, each with their unique transformation requirements.

Rewards: 1 Up-Grade and 1 Metal Coat

Eevee’s diverse evolutionary paths present both opportunity and challenge. For newer trainers, focus on evolving Eevee during daylight hours for Espeon and nighttime for Umbreon, as these don’t require special items. Vaporeon, Jolteon, and Flareon remain random evolves unless you use the specific naming tricks if available. Advanced strategy: Save evolution items for Pokemon that specifically require them, as Eevee’s elemental evolutions can be completed through random evolution or buddy walking methods.

Common mistake: Evolving Eevee without ensuring you have enough candy for multiple attempts. Always maintain at least 125 Eevee candy before starting this challenge to account for potential random evolution disappointments.

Trade Evolution Challenge Guide

The Trade Collection Challenge focuses on Pokemon that evolve through trading, requiring coordination with other trainers.

Rewards: 1 Dragon Scale, 1 Sun Stone, and 1 King’s Rock

Trade evolutions present unique logistical challenges. Coordinate with local trainers or friends to arrange mutually beneficial trades. Remember that traded Pokemon cannot be traded again, so plan your trades carefully. For Pokemon requiring items plus trading, ensure you have the necessary evolution item before initiating the trade.

Pro tip: Use community Discord servers or local Pokemon Go groups to find trading partners. Many trainers are completing the same challenges and may be looking for trade partners. Always check IV rerolls after trading, as stats change during the process.

Avoid the common error of trading away your best IV specimens, as trade evolution resets Pokemon IVs. Instead, trade medium-quality Pokemon and keep your high-IV candidates for other purposes.

Unova Collection Challenge Guide

Unova region Pokemon take center stage in this challenge, featuring species introduced in Generation 5.

Rewards: 4 Sinnoh Stones

The Unova challenge typically includes Pokemon like Timburr, which evolves into Gurdurr and then Conkeldurr, requiring trading for the final evolution. Other Unova species may include those needing specific evolution items or high candy costs.

Strategic approach: Prioritize Pokemon that appear in current raids or research tasks to minimize wild hunting time. Unova stones from this challenge’s rewards can be used for future evolutions, making this challenge particularly valuable for long-term progression.

Advanced tactic: Check your existing Pokemon storage for Unova species caught during previous events that may be close to evolution. Many trainers overlook previously caught Pokemon that could be evolved with minimal additional candy investment.

Sinnoh Collection Challenge Guide

Sinnoh region Pokemon feature in the final Collection Challenge, highlighting species from Generation 4.

Rewards: 2 Unova Stones

Sinnoh challenges often include Pokemon like Riolu evolving into Lucario, or other species requiring specific evolution items. The Unova stones earned here are extremely valuable for future Unova region evolutions.

Efficiency tip: Cross-reference your Sinnoh challenge requirements with current raid bosses and field research encounters. Often, event-specific research tasks provide exactly the Pokemon needed for these challenges.

Common oversight: Failing to check evolution item requirements before catching. Some Sinnoh Pokemon need specific items that may require farming from Pokéstops or completing certain research tasks. Plan your item usage across all challenges for maximum efficiency.

Advanced Collection Strategies

Most required Pokemon for these Collection Challenges appear as wild spawns during the Evolving Stars event, making completion reasonably accessible for active trainers.

When struggling to locate specific Pokemon, strategically deploy Incense and Lure Modules to maximize spawn rates. The nearby Pokemon tracking feature provides real-time location data for species in your immediate area.

Systematically using Pinap Berries when catching challenge Pokemon significantly accelerates candy accumulation, enabling faster evolutions. Designating required Pokemon as your buddy provides additional candy through walking distance.

The Evolving Stars event concludes on Tuesday, October 11, 2022, at 8 PM local time, providing approximately one week to complete all Collection Challenges.

Advanced optimization: Create a priority list based on spawn frequency and candy requirements. Focus on rare spawns first while using common Pokemon to farm candy through catches and transfers. Track your progress daily to identify remaining gaps with sufficient time to address them.

Time management strategy: Dedicate specific play sessions to hunting different challenge categories. Consider focusing on one geographic area with multiple Pokéstops to maximize Lure Module efficiency and spawn variety.
