Why this duo works
Lulu helps Rengar survive the risk of diving into the enemy team: Whimsy(W) and Help, Pix!(E) add speed and a shield, while Wild Growth(R) can add health and knock nearby enemies up as Rengar lands. That gives the jump both stronger follow-up and protection from the focus it draws.
Playing the duo
Rengar's leap gives Lulu a clear moment to cast Wild Growth(R) for a point-blank knockup; Whimsy(W) speeds his approach and Help, Pix!(E) shields him through the dive.
How to play as Rengar
Coordinate Thrill of the Hunt(R) before jumping so Lulu can follow your entry with Wild Growth(R). Avoid diving alone when her shield and ultimate are down; her buffs help you survive the focus after your first leap.
How to play as Lulu
Use Whimsy(W) to speed Rengar's approach, shield him with Help, Pix!(E) as he commits, and time Wild Growth(R) for when his leap lands so the knockup disrupts the enemy response.
