This guide provides a comprehensive analysis of the best investment options across all rarities, based on current gameplay performance and the latest trailer insights, covering Arena, PvE, and Guild content. It will help you plan your resources strategically and maximize long-term value.

Ancient Cookies

All five Ancient Cookies have now received their Awakened forms, but not all of them are worth investing in equally.

Recommended Investments

Name

Reason

Pure Vanilla Cookie

Pure Vanilla Cookie

One of the strongest healers in the game right now. He remains highly relevant across Arena and multiple PvE modes.

Hollyberry Cookie

Currently one of the best tanks in the game. While she was once considered weak months ago, recent changes have pushed her into a top-tier defensive role.

White Lily Cookie

White Lily Cookie

Continues to see consistent use across Arena and other game modes.

Not Recommended

  • Dark Cacao Cookie
  • Golden Cheese Cookie

These two are currently less impactful compared to the other Ancients and are not ideal long-term investments.

Beast Cookies remain extremely powerful, but some stand out far more than others in terms of overall value.

Most Legendary Cookies are currently niche, but a few are still worth attention.

Recommended

Millennial Tree Cookie( Brand-new Cookie)

Millennial Tree Cookie( Brand-new Cookie)

He provides strong team sustain through continuous healing, self-cleansing, and shielding. He also offers steady damage and a debuff on key enemies, adding both survival and control to the team.

Since he is a newly released Cookie with solid mechanics and strong scaling, it is reasonable to invest in him first.

Wind Archer Cookie

Wind Archer Cookie

A strong investment due to his effectiveness in PvE and boss stages. Most importantly, he is confirmed to receive a Crystal Jam, which is expected to bring him back into Arena relevance.

Fire Spirit Cookie

Fire Spirit Cookie

Performs well in certain situations due to strong damage output.

Situational

Sea Fairy Cookie

Sea Fairy Cookie

Used in Machine God Guild Boss and certain PvE stages, but requires Crystal Jam investment to remain viable.

Not Recommended

Pitaya Dragon Cookie

Pitaya Dragon Cookie

Still needs a significant buff and is not currently worth investing in.

Super Epic Cookies

Currently, most Super Epic Cookies are considered outdated. While they can still see occasional use in the Arena or for niche situations, their overall impact is limited. To become competitive again, many of these Cookies would require significant buffs or a complete system revamp.

Recommendation:

Avoid heavy investment in Super Epics for now.

Epic Cookies

Epic Cookies offer the widest range of viable investments, especially for Guild Boss and general PvE content.

Recommended

Twizzly Gummy Cookie

Twizzly Gummy Cookie

One of the best support Cookies in the game; highly recommended

Solid / Situational Picks

Prune Juice Cookie

Guild Boss usage

Black Lemonade Cookie

Strong buffer

Mint Choco Cookie

Effective at low investment levels

Some Epic Cookies benefit from Magic Candies, but most do not require maximum investment to perform well.

Special Cookies

Best Specials to Invest In

Marshmallow Bunny Cookie

Marshmallow Bunny Cookie

Cream Ferret Cookie

Cream Ferret Cookie

These two provide the most value among Special Cookies.

Limited Use

Collaboration Specials such as Almond Bar, Glinda, etc.

These can be collected and promoted, but they are unlikely to see long-term usage outside of specific events or Arcade Arena.

Final Thoughts

In summary, by identifying key investment targets and prioritizing versatile Cookies, you can gain an early advantage once the update goes live.
Following the recommendations in this guide ensures that your resource allocation delivers the greatest impact across Arena, Guild, and PvE content, keeping your team strong and adaptable for the challenges ahead.
