Zyra vs Lillia

Cast your spells on Garden of Thorns (passive) seeds: Deadly Spines (Q) grows a Thorn Spitter that fires at 575 range, Grasping Roots (E) a Vine Lasher that slows.

Cast Grasping Roots (E), then right away place a seed in its path with Rampant Growth (W): the target is rooted, and the plant that grows hits them.

Cast Stranglethorns (R) on your plants in the middle of the fight: enemies are knocked into the air 2 seconds later, and your plants, renewed, gain health and damage.

Place seeds with Rampant Growth (W) in brushes and near objectives: a champion who steps on one is revealed, and you can grow a plant there.

Against Blooming Blows (Q), stick to her or back out of range: only the outer edge of the zone adds true damage.

Get out of the center of Watch Out! Eep! (W): the zone deals much more damage there than at the edge.

Dodge her spells, even Swirlseed (E), which rolls to the first enemy: each one marks you for Lilting Lullaby (R), which puts every marked enemy to sleep.

If you have CC, use it on her: with no dash, she relies on the move speed Blooming Blows (Q) gives her for each spell that hits.
