How this board works
Each row is a mutation, ranked only by the factor published for it. A higher factor pays more on the same Brainrot with the same traits. It does not mean you can get that mutation today. Gold and Diamond are the ones new players actually see.
S tier
Player decision Highest published factor in this set. Only useful if the copy you can actually obtain says Celestial.
Player decision Strong when the Crystal event or a rerun is actually applying it. Otherwise compare the rate on the card.
Player decision Top of the factors that were already public before Crystal and Celestial. Still an event mutation, not a shop upgrade.
A tier
Player decision Keep a Cyber copy you already own. Do not assume the Cyber map event is still on a weekly timer.
Player decision Best widely discussed natural factor. Still rare. Do not pay an event-mutation price for a Rainbow unless the rates justify it.
Player decision Same published factor as Rainbow, different route. The look is the way to tell them apart, then the card.
B tier
Player decision Strong legacy factor. Availability is the limiter, not the math.
Player decision Treat as a legacy or admin variant unless you see it applied in the current server.
Player decision Useful on a copy you already have. Not a natural Gold-style roll in the later natural list.
Player decision Above Lava on the published scale. Confirm the label before you trade for it.
Player decision A clear step up from Candy and Bloodrot when the event is live or the copy already has it.
C tier
Player decision Fine on a unit you like. Weak next to Rainbow or any double-digit event factor.
Player decision Better than Diamond on raw factor, far behind Rainbow. Do not pay a premium as if it were current endgame.
D tier
Player decision The realistic upgrade most players should recognize. Check traits before you skip a Diamond for an unavailable 10Γ.
Player decision Worth keeping on a strong base character. A small factor on a high base rate still beats a huge factor on a Common.
