if you're going to go for CS against somebody, say nightmare,
which moves are the safest and deal the most soul damage?
CF* not CS.
The general plan I run for CF is:
SW mode
3B - 10 hits, spammable and safe
1_2_3B+K - 9 hits, safe when used properly
A+B - 10 hits and can go UB for mind games
FC 3B - 11 hits and good range
2B - 15 hits and good when doing a crouch
BB - 10 hits and good pressure string to force blocking
WS B - 10 hits and good RO tool
CL mode
33_99bB - 9 hits and is a great anti wake up pressure
6B - 10 hits and good long range poke
214B - 11 hits and is Unsafe, but naturally will occur trying to land a hit...never attempt for CF pressure unless you're OK with risking the punish
6A+B - 10 hits and VERY good long range poke and safe if done right
WP mode
6B - 10 hits, fast long rang poke that is safe when done right.
6B+K2_8 - 9 hits and is safe from long range. DO NOT SPAM at mid range when at disadvantage!
66B - 10 hits and has good range and speed
All these moves are good on their own and should be used for gaining damage normally, but at the same time yield great CF potential on turtles.
