Pyke vs Janna

Charge Bone Skewer (Q) from a brush or the fog of war: when held, it pulls the first enemy hit, and refunds mana if it hits a champion.

Dash through your target with Phantom Undertow (E): the phantom left behind returns to you and stuns champions in its path.

After a trade, get out of their vision: Gift of the Drowned Ones (passive) regenerates the damage champions just dealt you.

Cast Death From Below (R) on a target below the threshold: each champion who dies in the X lets you recast it, and your last assisting ally also gets the kill gold.

Roam or flank with Ghostwater Dive (W): you're camouflaged and gain a lot of move speed, which decays over time.

Avoid trading while her ally has Eye Of The Storm (E): the shield absorbs your damage and gives them AD.

Bait out Howling Gale (Q) or Monsoon (R) with a first engage, then re-engage right away: one has a 14-second cooldown, the other 130 to 100 seconds.

If you have CC, save it for Monsoon (R): after the knockback, she heals her allies as long as she stands still, and interrupting her cancels the heal.
