Poppy vs Irelia

Position so that Heroic Charge (E) slams your target into a wall: they're then stunned and take bonus damage.

Keep your target in the Hammer Shock (Q) zone: the zone slows them, then explodes and deals the same damage a second time.

After a trade, pick up the Iron Ambassador (passive) buckler that bounced off your target: it gives you a temporary shield.

Cast Steadfast Presence (W) when an enemy is about to dash onto you or your carry: the field stops dashes around you, and the stopped enemy is slowed and grounded.

Charge Keeper's Verdict (R) to send away a diver or isolate their carry: the target is knocked back toward their Nexus, farther the longer you charge.

Don't stand near your low-health minions: Bladesurge (Q) resets when it kills, so she chains dashes from minion to minion until she reaches you.

As soon as the first blade of Flawless Duet (E) lands, change direction: the stun only hits enemies caught between the two blades.

Take your trades when Ionian Fervor (passive) isn't stacked: she builds stacks with her abilities, and at max stacks her autos deal more damage.

Save your burst for after Defiant Dance (W): while charging, she takes much less damage, but she can't do anything else.

Dodge Vanguard's Edge (R): its blades make you Unsteady, which resets Bladesurge (Q) on you, and the cage they form damages and slows anyone who crosses it.
