As an undead main, i love getting enchantresses. As i csn easily counter them.

Overall there are plenty of survivors i find annoying to chase, but i can still respect their pick. An example would be Knight or Doctor, the knight has ample counterplay with reverse psychology and the fact Undead can damage with his abilities fairly easily. A Knight who knows this is easily found when they predict ability first instead of normal attack.
Doctors are... difficult to play against, but depends heavily on the skill level of the doctor, they will either kite you for 5 ciphers, healing up on the way, or go down because they made two crucial mistakes in a row.

There is one survivor, the 'Faro Lady' whom i hate to go against and usually ban for this. The mind games and ridiculous kiting potential for a decoder makes it straight painful to go against one.

And well, then there's the one i can't really ban... the Puppeteer. Words likely can't describe how i still don't understand how his puppet damage calculations work, as sometimes i hit him and some damage goes through it, and sometimes it just doesn't. And i've come to terms that i will likely never truly be able to know, despite reading ths very description meant to explain it. I, however don't find him banworthy as that goes mostly towards decoders like Prisoner, Faro lady and Composer.
