Rival Rengar

Rival Rengar is a slow-roll board: hold your economy at level 7 and dig for Kha'Zix, a 3-cost unit you want at three stars before pushing levels. 1,381 ranked games deep, the average sits at 5.19 — a Tier D showing for Set 18.

Set against the full field it lands at #42 of 53 and, as 3rd of the 14 boards holding that tier, ahead of its tier's 5.48 median by 0.29. It flies under the radar at a 0.1% pick rate versus a median of 0.49 percent, so its units usually come uncontested.

Kha'Zix is the board's item carrier; recorded games favor Archangel's Staff, Edge of Night, and Hand Of Justice on it. Your next-best item holder is Rengar.

The synergy sheet lists 3 active traits here, topped by Inferno at 3, with Rival at 2 in support. There is latent Defender on this board — 1 unit, not yet active, so a Defender Emblem turns it on at the 2-piece tier.

Our model's emblem pick for this exact roster is Defender Emblem — then Juggernaut Emblem. Asked the other way — “I found a Defender Emblem, what do I play?” — this board ranks #19 of the 26 comps our model scores for it.

Hunter Sivir Nidalee and Vanguard Aphelios share the Rengar core with Rival Rengar; if another player commits to Rengar first, one of you should be pivoting.

The 1,381-game sample is thin by this patch's standards; read the averages as an estimate, not a verdict.
