Here is The Arena's Viability Ranking of Corrupteds from OP Rank to F Rank. OP is the most useful choice on your team and F is not recommended. Only Corrupted monsters are covered in this ranking.
This list is based around monster's performance in The Arena (PvP), NOT Team Wars, Duels, etc. The monsters are also ranked at Rank 5. While we try to keep this list as objective and accurate as possible, these rankings are purely community-made. Please use this list as a supplementary teambuilding resource rather than an official and factual ranking.
The monsters here are considered so stupidly overpowered that they literally get their own tier. These monsters are on a league of their own and make nearly all monsters viable.
|Chi Ao Loong||Pure Pandalf|
Some of the best monsters in the game, beaten out by only the OP tier monsters but despite that, they still are incredibly recommended monsters to you when you want to aim for the highest ranks.
Outstanding monsters that fit in the meta nearly perfectly but get outshined by a few other monsters.
Amazing monsters that perform nicely in the meta but are slightly worse than the ones above.
These monsters are incredibly viable picks, beaten out only by the SS and OP monsters. They perform really well in top-level play and tend to make up the bulk of the meta. They are highly recommended for anyone who aims to be competitive at a high level.
These monsters are barely worse than the S tier monsters. Even so, they should still be highly considered when building a team. They are perfectly viable picks for top-level play, though they have a few more weaknesses than monsters in S.
These monsters are also solid picks for teams in the meta. They are slightly worse than the monsters in AA, but can perform nearly as well in PvP.
|Boomshakalaka||Elfriede||Gobzlayer||Kernel Pip||King Charmless||Kurai Kage||Master Rat|
Pretty good monsters that can act as a substitute for some of the higher tier ones.
|Sensei Pandaken||Sir Valgar||TomSka's Mine Turtle||Yaoguai Wangzhou|
Neither great nor bad, these are decent monsters that can perform well in some scenarios. They aren't horrible, but they lack a powerful gimmick, which puts them at a disadvantage in the meta.
These monsters are generally bad and should be avoided unless you don't have the higher tier monsters. They can perform decently with the right allies but are just not fit for the meta. They are also outclassed by most of the high tier Cosmics.
These monsters are bad and cannot work as decently as the monsters in the tier above. However, they have slightly less flaws than the monsters in F tier.
Monsters in this tier should almost never be used in competitive play. They are completely horrible and perform miserably in the arena. Many of the Cosmic monsters, and even a few Mythics, outclass these monsters.
