What does the tier list look like?

Generalised modern list

Many players have different views on a tier list for Karnov's Revenge, the one above shows the general picture. Playerbase's opinions usually diverge from this point forward. Keep in mind that this is a "general picture", matchup knowledge in FHD is much more important for understanding the game.

~2019 list

Top	Ray, Lee, Zazie, Karnov
Upper-Mid	Jean
Mid	Mizoguchi, Samchay, Yungmie
Lower-Mid	Matlok, Clown, Feilin
Low	Marstorius, Ryoko

The placement of Marstorius in the tiers is one that there are rarely agreements on - some think he could be as high as Upper-Mid, others think he's much lower (one Japanese tier listing had him ranked as dead last). He has some very tough matchups and it can be hard for him to get in on characters with projectiles, but once he gets in he has a nasty mixup game that can easily win him the round. So he's a bit of a wildcard since a lot of his matches can go either way.
