Elf

Overview
Elf is a defensive marksman which specializes at outranging opponents. Elven Sight extends the range of Elf's basic attacks and shifts the player's point-of-view to first-person. This allows the Elf to snipe enemies from afar with great accuracy.

In addition, Elf has decent escape tools against enemies who get close. It can dodge most threats with Elven Leap and is likely outrun pursuers thanks to the mobility buff from Elven Agility.

Elf pays for its strong defense by having a weaker offense. While Elven Sight helps defeat enemies by outranging them, Elf can't damage Turrets and Golems during Elven Sight. In other words, Elf doesn't have any steroid abilities to boost its weak offense. As a result, its DPS against towers is lower than average for a marksman and that makes it harder for Elf to carry.

Because of that, Elf is usually either picked as a counter-pick against aggressive opponents or as a safe addition to late-game composition.

In the Novel
During the match against the Leopards' second string, Albert (SkyNight), picked Elf to counter Trever's Ranger. It was a counter that was based on range. Elf specialized at attacking from afar while Ranger wanted to get closer and CC the opponent. This counter-pick worked well and contributed toward Trever's gradual deterioration in that scrimmage.

When Lars played against the Leopards' second-string, Yuel made him pick Elf after Trickshooter was banned. This was a defensive counter-pick to ComboBreaker's burst combos. Lars didn't have an alternative class he played on par with Trickshooter at the time, so Elf was a safe pick which was supposed to keep him safe from Breaker's combos.

However, Jennifer (ComboBreaker) picked Pirate for that last game. She was confident she'll be able to easily play such a "basic meta class". However, turned out she lacked matchup knowledge of Pirate vs. Elf. Both classes are weak in the early-game and usually should play safe during this phase, but Pirate actually has the upper hand in this matchup and should aggress more to bully the Elf. Breaker didn't know this, so that became her undoing against Lars.
