Irelia vs Gnar

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.

Take your trades when he's Mini Gnar with little Rage Gene (passive): he then has no stun and none of Mega Gnar's defenses.

Dodge Boomerang Throw (Q): it slows you, and if he catches it on the way back, its cooldown drops.

Take short trades: on every third auto or ability that hits you, Hyper (W) adds damage based on your max health.

Stay away from walls against Mega Gnar: GNAR! (R) knocks back every nearby enemy, and those who hit a wall are stunned.
