How Many of Each Pokémon Should I Keep in Pokémon GO?

As an avid Pokémon GO gamer and content creator, I‘m often asked – just how many of each Pokémon should players be keeping? With frequent new releases flooding limited storage and constraints on powering up multiples, it‘s an important question. After playing since 2016, I recommend focusing on 6-12 top attackers and defenders, plus 1-2 of your highest CP/IV catches of other species.

Building a Battle Ready Roster

Instead of an unrealistic goal to "catch ‘em all", your Pokémon GO priorities should be building a lean, mean, battle-ready roster. In the main series games, your fighting party tops out at 6. With GO allowing parties of up to 12, you realistically only need a subset of meta relevant Pokémon powered up:

According to Pokebattler raid analysis and PvPoke rankings, the top performers comprise a relatively small pool of Pokémon. As a rule of thumb, I recommend owning at least 3-6 powered up copies of those species. This offers flexibility to build optimal type-advantaged teams without splitting resources too thin.

Per The Silph Road research, the gains from powering up multiples of the same species see diminishing returns. From a stardust perspective, taking a mediocre IV Pokémon to level 30 costs nearly as much as maxing out that 100%.

In most cases, I‘ve found powering up more than 1-2 of a species winds up being prohibitively expensive for minimal stat boosts. Those resources are better spent building out a versatile roster.

If we visualize the ideal Pokémon distribution, your powered up arsenal should resemble something like this:

As you can see, top performers make up the majority share, while second-stringers get far less representation.

Transferring Duplicates

Adhering to a 1-2 top CP and IV policy per species is prudent for long-term storage management. While variety helps fill the Pokédex, maxing out multiples dilutes your stardust and candy without significant Returns on Investment (ROI).

As a collector at heart, letting go of duplicates took me time to embrace. But with frequent special research, events, nest migrations, and new releases flooding our rosters, space becomes limited fast. During certain events I‘ve hit the cap, preventing catching event spawns without mass transfers. A tough but important habit I‘ve learned is periodically clearing house of excess Pokémon to open up storage room.

Making Room for New Releases

Since Pokémon GO‘s launch, there have been four generations of new Pokémon released via a combination of events, nests, raids, eggs, and regionals. With Gen V just 59% released, consider:

• 153 Unova Pokémon remaining
• Estimated at least 100 from future Gens 6+
• Continued rollout of shinies, special costumes, exclusive moves

As veterans know, Niantic turns the new release spigot on full blast during events, overloadings rosters fast. My recommendation? Get in the habit of regularly transferring duplicate species to clear space for each wave of new arrivals.

Yes, it‘s hard. I still feel occasional pangs of FOMO (fear of missing out) releasing 100% or sentimentally named Pokémon. But embracing minimalism makes space for what matters most – beasts ready for battle!

Special Exceptions

While the 1-2 copy rule applies generally, there are some exceptions to consider:

Trading fodder – Regionals, spare legendaries, and spare shines make excellent trade bait for lucky trades. Worth hanging onto a few extras of the heavy hitters.

Exclusive/Legacy Moves – Pokémon with elite charge moves not currently obtainable (Psychic Alakazam, Rock Wrecker Rhyperior etc.) warrant keeping/powering multiples.

Personal Favorites – We all have niche Pokémon that hold special sentimental value. Nothing wrong maintaining a couple small personal collections on the side (baby Pokémon for me!)

In Conclusion

As a Pokémon GO gamer and content creator playing since day one, I recommend adhering to a few key rules of thumb for maintaining storage:

• Focus resources into 6-12 top counters for raids, gyms, league metas
• Adopt 1-2 of your highest CP/IV policy per species. Outside top performers, powering extras generally inefficient
• Transfer duplicates and weaker Pokémon on a regular basis to clear space
• Make occasional exceptions for special cases like trading fodder and sentimental favorites

While a completionist approach sounds appealing in theory – trying catching and maxing out every Pokémon alike – it isn‘t realistic or possible. By embracing a minimalist approach focused on offense and defense, you can build a strong, lean team ready to strategically dominate every battle challenge.
