Zoe

Strengths

Paddle Star deals more damage the further it has flown. Casting it behind yourself before redirecting can deal tons of damage.
Break Sleep with your biggest damage source, since enemies who are asleep take double damage.
Sleepy Trouble Bubble travels further over walls. Find a hiding spot to set up for a long distance kill.

Passive · More Sparkles! — Zoe's next basic attack after casting a spell deals bonus magic damage.
Q · Paddle Star! — Zoe fires a missile that she can redirect in flight. Deals more damage the longer it flies in a straight line.
W · Spell Thief — Zoe can pick up the remnants of enemy summoner spell and active item casts and cast them once herself. Whenever she casts a summoner spell, she gains 3 missiles that fire at the nearest target.
E · Sleepy Trouble Bubble — Causes the target to become drowsy, then fall asleep. While asleep, the target's Magic Resist is reduced. The first source of damage that breaks the sleep is doubled, up to a cap.
Ultimate · Portal Jump — Blink to a nearby position for 1 second. Then blink back.

A suggested 5-lane lineup built around Zoe, based on hero partnerships and role synergy — not win rate.
