Amumu has no dash, so a missed Bandage Toss (Q) leaves him defenseless; Ekko slips his Bandage Toss (Q) and Curse of the Sad Mummy (R) combo with Phase Dive (E) and overwhelms the late-game duel with Chronobreak (R)'s healing and scaling.

Nunu's Biggest Snowball Ever! (W) charge and Absolute Zero (R) are both telegraphed, so Ekko dodges them with Phase Dive (E) and flips long duels with Chronobreak (R)'s healing.

Sion's charged Decimating Smash (Q) is slow and he has no dash, so Ekko sidesteps it to kite and safely bursts him down with a Parallel Convergence (W) stun setup.

Maokai has no dash, so Ekko dodges his Sapling Toss (E) and Twisted Advance (W) root with Phase Dive (E), staying ahead on skillshot-dodging tempo and late-game burst duels.

Lee Sin's Sonic Wave (Q) into Resonating Strike (Q) followed by a Dragon's Rage (R) combo, plus early invade pressure, pushes the weak pre-5 Ekko off camps and dominates the duel.

Xin Zhao's third-hit knock-up from Three Talon Strike (Q) and the healing from Determination (P) win every early duel against Ekko before items come online.

Olaf becomes immune to Ekko's Parallel Convergence (W) stun with Ragnarok (R), and overwhelms extended duels with Undertow (Q)'s slow and Berserker Rage (P)'s sustained damage.

Warwick's Eternal Hunger (P) lifesteal and Blood Hunt (W) chase speed let him latch onto Ekko and never let go, while Infinite Duress (R)'s guaranteed CC dominates early extended fights and ganks.

Graves' point-blank buckshot burst from End of the Line (Q) beats item-less early Ekko's all-in, and his strong early stats give him the invade advantage.
