The soft, white fur of the Cinccino is capable of deflecting a great many types of attacks, and has stymied many an opposing trainer. Cinccino are virtually immune to an expanding, never-ending list of types and attacks which many find impossible to keep up with. But as their failure to dominate the high ranks of the Unovan Pokemon League compellingly demonstrates, these pokemon, much to the chagrin of their trainers, are not actually invincible.
Despite the remarkable deflective power of their white scarf, most Cinccino fur is gray and not particularly absorbent, and the key to defeating a Cinccino is to take advantage of that fact. This can be done through either focused attacks too quick for even a Cinccino to move their scarf in time, or more commonly through wide-ranging attacks of which a Cinccino's scarf is not wide enough to absorb more than a small portion. These weaknesses are known to elite trainers, who have inevitably learned how to get past a Cinccino, but many individuals remain stalled at the lower levels, either because they can not figure out how to defeat a Cinccino or because they lack pokemon capable of actually beating them.
Every pokemon has their weaknesses, and not solely in type matchups; this exploration of them is not to suggest that discovering Cincinno's turns them into pushovers. Although these pokemon do struggle with many common high-level attacks, such as Earthquake, others such as Ice Beam are too narrow to damage them. A few Cinccino trainers use items such as Brightpowder and attacks such as Double Team to maximize their evasion and learn to win at the highest levels, but many others, so accustomed to dominance in their early careers, struggle to adapt to opponents who have figured out to fight back.
