Irelia vs Poppy

Mark your targets with Flawless Duet (E) or Vanguard's Edge (R) before Bladesurge (Q): if the target is Unsteady or dies to it, its cooldown resets.

Before a trade, hit minions with Bladesurge (Q) to stack Ionian Fervor (passive): each stack gives attack speed, and at max stacks your autos hit harder.

Place the two blades of Flawless Duet (E) on either side of your target: only enemies caught between them are stunned.

Use Defiant Dance (W) to absorb a burst: you take less damage while charging, and the longer you hold it, the harder the release hits.

Stay away from walls against her: Heroic Charge (E) stuns you if she slams you into an obstacle.

Step on the Iron Ambassador (passive) buckler when it lands: she can no longer pick it up, so she doesn't get her shield.

If you have a dash, don't use it near her during Steadfast Presence (W): the field stops it, and you're slowed and grounded.

If you have CC, use it when she spins her hammer for Keeper's Verdict (R): the longer she charges, the farther she sends her target.
