- Zed harass combo: W --> E --> Q or W --> Q --> E. I often use W+E+Q 'cause W+E will slow your enemy then you can easily aim your Q!
- Full combo with Death Mark:
. W + E --> W in --> R (to dodge a skill. Ex: Orianna Ult herself) --> Q + E. Otherwise, if your enemy (likes Orianna) wait for you to R in then uses their CC, you can Death Mark (R) then press R again instead to avoid it, then throw the shuriken with your Death Mark's shadow.
. R + W --> R (to dodge CC) --> W again (to get back)--> E + Q. Or you can use first R to dogde something --> W --> E --> Q --> R to get out. R --> W --> E --> Q is the most powerful combo 'cause you can easily hit enemy with 3 shuriken and trigger your passive.
. W --> R --> R --> E + Q --> W again to auto attack - put the use of passive. I often use this combo when I'm really really low and the opponent is a full health ADC tryin' to catch me. This make them confused and cannot touch you.

It's all about dodging projectiles and outplay your opponent when playing Zed! Remember that you have your shadow (W) and your Death Mark that can dodge a lot of bursting skill and make them confused :)
