Tryndamere vs Irelia

Keep your Fury high before a trade: with Battle Fury (passive), it raises your critical strike chance. Spend it with Bloodlust (Q) when you need health.

Cast Mocking Shout (W) before a trade against a physical damage champion: it lowers their attack damage, and slows enemies who turn their back on you.

Count on Spinning Slash (E) to stick to your target or to escape: each critical strike lowers its cooldown, more so on a champion.

Wait until you're close to death to cast Undying Rage (R): you can't die during the effect, and delaying it pushes the enemy to take risks to kill you.

Split push in a distant lane to draw several enemies: Undying Rage (R) helps you hold them off while your team takes an objective.

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.
