Hecarim S Back to Basics massively boosts Q damage — paired with other damage amp hexes, Q hits like a truck. 
Graves S Graves's autos on the same target don't reset Don't Blink charging — every auto carries the on-hit; Stormrazor extends range. Graves S Convert Graves's massive AP into bonus physical on-hit via Marksmage. His autos fire 4 pellets, each triggering independently — one auto = +300% AP. Late-game with Ruined King pellets become 6 for 4.5x AP scaling. Only viable when first hex is Marksmage; otherwise pure AD outperforms. Bonus damage is physical, so Black Cleaver is core late. 
Briar S Crit build deals huge damage — lifesteal heals you to full through Grievous Wounds in two bites. 
Viego S Drop Hubris/Liandry's tradition — go crit + armor pen. Use Collector + IE + Jeweled Gauntlet from Mayhem hexes to max Q/R damage for instant kills. Skip Hubris — Viego doesn't get the kill credit after possessing. Better burst for instant kills vs long-range comps. 
Bel'Veth S Bel'Veth's Q and W are AoE — multi-hits cut multiple CDs, making QWE basically zero-CD. Infinite QW knockup. 
Xayah S Forge: omnivamp > AS > armor pen > AD > MS. 
Yasuo S Huge MS and heal/shield uptime. Keep exploring
