Rek'Sai is an early tunnel ganker and invade jungler who must leverage her very high early game pressure to disrupt Evelynn's weak pre-6 clears.
Prioritize aggressive early pathing and river control to prevent Evelynn from safely reaching her level 6 power spike and stealth threat.
Jungle Plan
Use fast clears and tunnel placement to maintain tempo and pressure Evelynn's jungle camps before she can scale.
Invade Evelynn early when lanes can assist or when she shows on the opposite side of the map to deny her farm and delay her level 6 spike.
Prioritize early dragon control and use vision denial to limit Evelynn's post-6 flanking potential around objectives.
Danger windows
Avoid invading or contesting river objectives when Evelynn hits level 6 and gains camouflage and charm (W), increasing her kill threat.
Be cautious during low-health clears or forced smite fights where Evelynn can leverage stealth to flank or force unfavorable trades.
Watch for Evelynn's post-6 cross-map ganks on pushed or flashless lanes; maintain vision and lane priority to reduce counter-gank risk.
Early game
Start with a three-camp clear into an early invade or countergank to capitalize on Rek'Sai's high early game pressure and Evelynn's low invade resistance.
Fight for first Scuttle when nearby lanes have priority to deny Evelynn vision and control of river objectives.
Avoid prolonged river fights if Evelynn reaches level 6 first, as her camouflage and charm (W) create dangerous pick opportunities.
Power spikes
Rek'Sai's level 3 with three-camp clear enables strong early ganks and invades; use (W) knockup and (R) execute to secure kills or force summoners.
Evelynn's level 6 unlocks camouflage and (W) charm, increasing her pick threat; respect this by avoiding isolated river fights.
Rek'Sai's early power spikes allow her to snowball leads before Evelynn's AP scaling and stealth become a threat.
Win conditions
Convert early tunnel ganks and invades into objective control by securing dragons and Rift Herald before Evelynn scales.
Use superior dueling and gank threat to deny Evelynn farm and delay her level 6 power spike.
Maintain river vision and pressure to limit Evelynn's stealth flanks, forcing her into teamfights where Rek'Sai's early game strength can dominate.
