S is always for Sam
Sw is for Skel workers ( A capital 'S' and a small 'w')
Skel Workers do 15% more damage to medium sized monsters only and give +5 attack to the final damage.
Turtle General does 20% more damage to everything.
Samurai give 65 Attk which is an absolute value
Turtle general gives 20% of your current attack which is a variable value.
Bapho is always used with Sam because the effect of Turtle Card does not spalsh while that of the Samurai cards splash.
If you are on an Assassin character -chances are the your total attack is lower then 325 meaning you can use Sam cards for better effects.
If you are on a Swordy,hunter or a Smith class your attack will be over 325 making Turtle general a better option damage wise.
Lets say you have 1000 Base attack
With sam it becomes 1065
while with 1 Turtle general it becomes 1200 (1000 +20% of 1000 (which is 200) = 1200)
=======If you understood the above part then read this part===============
There is something called as compounding which can be used to enhance damage against one race or size of monsters.
For Example in PVP
4 TG cards
1000+ 400 = 1800 Dmg
2 TG + 2 Hydra cards(Hydra work on a different multiplier so they compound on the toital ddamage from two TGs)
1400 = from 2 TGs
1400+280X2(from two hydras) = 1960 dmg
