|---|---|---|---|---|---|---|---|
 Ahri | Not Favored | 247 | 51% | +9 | -354 | You and Ahri share the same attack range, so the early lane is about who is more aggressive. Position behind minions to negate her E and focus on farming. Her Q is relatively easy to dodge. A standard build path is effective here. | |

 Yasuo | Very Hard | 156 | 45% | -281 | -972 | ||
 Viktor | Very Hard | 134 | 47% | +7 | -466 | Respect his oppression and early damage. After the first three levels, you can win extended trades and out-sustain him with Conqueror. He is relatively immobile, making him an easy target for ganks with your W. | |
 Ryze | Easy | 131 | 61% | +333 | +111 | This is one of your best matchups. Your W makes it much easier to land your Q. When he looks to use his W, you can counter with your R, as he will be facing you. | |
 Zed | Very Hard | 115 | 45% | -495 | -1,607 | You can establish dominance at level 1 by weaving auto-attacks between your E casts. Stand to the side of the minion wave so he has to choose between last-hitting or poking you with his Q. When he uses his R, throw your W at your feet; he will appear behind you and be grounded, allowing you to lock him down. | |
 Syndra | Very Hard | 114 | 53% | -357 | -1,643 | She has a significant range advantage and can poke you easily with her Q. She lacks mobility and is therefore vulnerable to ganks. Save your W for when you can close the gap or to support your jungler. Capitalize on the window when her E is on cooldown. | |
 Yone | Easy | 112 | 61% | +224 | -63 | ||
 Sylas | Easy | 110 | 49% | +137 | +269 | Punish him early by weaving auto-attacks between your E casts. Your W will not stop the second part of his E. If you are able to land your R, immediately follow it with W before using your Q and E. | |
