Tips to maximize your impact

Farm with your trident
Last-hit minions with Seastone Trident (W) early on: if the empowered auto kills, you get mana back and its cooldown drops.
Dodge with Playful
Save Playful (E) to dodge a key spell: you're untargetable for 0.75 seconds, then land with damage and a slow.
Throw your fish from range
Cast Chum the Waters (R) from range: the farther the fish travels before it attaches, the stronger the shark's slow and damage.
Combo before the shark
After Chum the Waters (R), chain Urchin Strike (Q) and Seastone Trident (W) while the target is slowed: the shark then bursts up under them and knocks them into the air.

How to counter and exploit weaknesses

Trade before he hits 6
Take as many trades as you can before he hits level 6: without Riftwalk (R), he has no way to move quickly, to engage or to escape.
Lean on physical damage
If you deal physical damage, lean on it in trades: Void Stone (passive) and Null Sphere (Q) only reduce magic damage.
Drag it out when he chains R
When he recasts Riftwalk (R) back to back, back off and drag the teamfight out: each quick recast doubles its mana cost, and once he's out of mana he can't blink anymore.
End the game early
Look to end the game early: at max rank, Riftwalk (R) only has a 2-second cooldown, and he blinks almost nonstop.
