How to play as Hwei
Push and poke as Mel approaches the wave instead of trading in the middle of lane. Bait Rebuttal with a low-commitment cast, then commit your ultimate or all-in only after W is down.
Do not throw EW directly into Mel's ready W; its delayed projectile can be reflected back at you. Use ground-based control or wait for her reflect before starting the combo.
Mel's Rebuttal(W) blocks and reflects projectiles; a well-timed cast can negate Hwei's committed ultimate and may send his delayed EW back toward him.
How to play as Mel
Save Rebuttal for Hwei's committed ultimate or EW projectile. If you reflect EW before it lands, the root can be sent back at Hwei and create a countertrade window.
