Tristana

Draw a Bead is the whole champion: Tristana's attack range grows every time she levels. Modern League dropped that mechanic, and having it back completely changes how the lane is played. Early on you are the shortest marksman in the corridor, late you are poking targets who simply cannot answer.

The rest of the kit serves that curve. Rapid Fire is an attack speed burst on demand, Explosive Charge makes your shots detonate on nearby minions and, activated on a champion, deals damage over time while cutting the healing they receive. Rocket Jump carries you over a wall and slows on landing, and Buster Shot knocks the target away from you. She's the one marksman on this roster whose ultimate is primarily a defensive button.

Her late game is among the best in the mode. Maximum range, attack speed on demand and a reliable escape: very few carries get to position that comfortably in a fight. Explosive Charge makes her one of the cleanest answers to compositions that live on healing, and her wave clear is instant. Buster Shot is a survival button that throws the assassin who just landed on you back across the scrum.

Her first ten minutes are a punishment. Your starting range is short, your damage per shot is poor, and poking costs mana you don't have. Rocket Jump is your only movement, so using it to attack means having nothing to leave with. And Buster Shot, badly used, literally rescues your target by launching them out of your team's reach.

Accept being behind until the middle of the laning phase. Don't look for the auto attack trade you lose: farm, hold the wave near the middle and let your range climb with your levels. Every level you take is a literal step closer to your opponent.

Use Explosive Charge on the enemy carry when he steps up for a last hit, not on cooldown: the damage over time plus the healing cut undoes his support's whole job. Save Rocket Jump exclusively for escaping a gank or a hook, jumping in to secure a kill is the fastest way to die in your own lane. Rapid Fire is for shoving a wave quickly so you can go replace your vision, or for finishing a weakened tower before their rotation arrives.

Your real spike isn't an item, it's your level. As the game runs on, the gap between you and your lane opponent widens on its own, until you can poke without ever entering their range. She's the only marksman in the mode who gains power purely by gaining experience.

The first item that matters is Infinity Edge: paired with Rapid Fire it turns your burst into something no marksman defensive item catches up with. Phantom Dancer follows and hands you the movement speed your positioning lacks. From two crit items onward, how fast you take a tower becomes strategic pressure in its own right.

Your range lets you stand further back than other marksmen, so use it instead of copying their positioning. Sit at your maximum distance, attack the closest reachable target, and never use Rocket Jump to enter. That button is your exit, and you only get one per fight.

Buster Shot deserves a second of thought before you press it. The good use is knocking away the assassin or initiator who just landed on you, creating the gap your support can't create alone. The bad use is firing it at a fleeing target on low health, which puts them out of reach of your entire team. When in doubt, hold it: a living carry beats a stolen kill.
