Laning Against Alistar: Strategies for Diana and Kayn
Early Game Strategy

Diana:
In the early game, Diana should focus on farming and trading safely against Alistar. Alistar's primary threat lies in his ability to crowd control with Pulverize (Q) and Headbutt (W) combo. To mitigate this, position yourself carefully and use Crescent Strike (Q) to poke and farm from a distance. When Alistar engages, utilize Pale Cascade (W) to absorb damage and retaliate with basic attacks and Moonsilver Blade (Passive).

Kayn:
Kayn's early game revolves around farming and preparing for his transformation. Against Alistar, use Reaping Slash (Q) to farm and dodge his engage attempts. Blade's Reach (W) can be used to poke and slow Alistar from a safe distance. Maintain a safe distance from Alistar to avoid his crowd control combo and use Shadow Step (E) to maneuver through the terrain, escape dangerous situations, or set up ganks.

Mid Game Strategy

Diana:
As Diana starts to gain items and levels, her burst potential increases. Look for opportunities to roam and secure kills. In team fights, wait for Alistar to use his crowd control abilities on other targets before engaging. Use Lunar Rush (E) to dive into the backline and Moonfall (R) to initiate or follow up on engages. Diana's burst can quickly eliminate squishy targets, making her a threat in mid-game skirmishes.

Kayn:
By mid-game, Kayn should have completed his transformation into either Rhaast or Shadow Assassin. As Rhaast, focus on sustained fights and diving the enemy backline, using Reaping Slash (Q) and Blade's Reach (W) to deal damage and heal. As Shadow Assassin, look for opportunities to pick off isolated targets with Umbral Trespass (R) and burst them down. Use Shadow Step (E) to position yourself advantageously and escape after engaging.

Late Game Strategy

Diana:
In the late game, Diana excels in team fights and can turn the tide with a well-timed Moonfall (R). Focus on assassinating key targets such as the enemy ADC or mid-laner. Coordinate with your team to engage when Alistar's crowd control abilities are on cooldown. Use Zhonya’s Hourglass to survive after diving into the enemy team, allowing you to continue dealing with damage and applying pressure.

Kayn:
Late game Kayn's strategy varies based on his transformation. As Rhaast, you are a frontline bruiser who can sustain through extended fights. Focus on disrupting the enemy team and healing through damage with Reaping Slash (Q) and Blade's Reach (W). As Shadow Assassin, prioritize flanking and eliminating squishy targets. Use your high mobility to engage and disengage swiftly, maximizing your burst potential.

Team Fighting and Initiation Tactics
Diana:
In team fights, Diana's role is to dive into the enemy backline and apply immense burst damage. Initiate fights with Moonfall (R) to group enemies and follow up with Pale Cascade (W) and Crescent Strike (Q) for maximum damage. Ensure to use Zhonya’s Hourglass after engaging to avoid being instantly focused. Diana thrives in teams that can follow up on her initiation, so coordinate with allies for the best results.
