+Perfect escape mechanism -hard to use his playful/trickster(e)
+Good early dmg with combo -difficult to hit ultimate
+low cooldown -less Dps
+a perfect skill called seastone trident -not too good passive (i think)

you can go utility for powerful lane control or you can go offens for faster kills your combo,give you fast kill and escape first use trident(w) and use urchin strike (q) your oppenent than some basic atck use playful/trickster(e) and finish him.

you can go mid solo in third lv fizz goes some harrass if your rival can't very powerful
you can kill him/her.
