Qiyana S Stack the Archmage hex, then loop Qiyana W (resets Q + adds an element) with Archmage's CDR returns for infinite QW combos. At 100+ ability haste it becomes a perfect cycle — endless dashes, stealth, or CC. Manamune is critical since infinite QW drains mana fast. 
Lux S Pure AP is squishy and damage-light — go half-tank and stack CDR for faster passive procs. Use R to clear waves. 
Nami S Q and R both proc Cruelty multiple times with their AoE. 
Morgana S Morgana's Q and W cooldowns overlap heavily. With Archmage's Q-reduces-W / W-reduces-Q loop, you can perma-root and burn enemies. Only ~80 ability haste needed for infinite QW — high tolerance, miserable to play against. 
Ashe S Ult has high AP scaling and deals magic damage. 
Ornn S Build around Fey Magic + Ornn's first R hit. Fey Magic procs Brittle 4 times on first ult — Brittle's 18% max-HP magic damage stacks four ways for 72% max HP, then magic pen + amp items finish the kill. Forge: ability haste > magic pen. At ~500 haste, Fey Magic is ~15s CD and ult is ~16s — every fight is a nuke. Build straight magic pen + damage amp. 
Trundle S R deals % magic damage — level 3 base is 30%, +16% at 800 AP, and 3500 AP hits 100% max HP. 
Hwei S Every Hwei E procs Cruelty — EE especially pulls enemies into one spot. Since Cruelty is AoE, grouped enemies eat stacked Comet damage. After EE pulls them in, the more bodies, the more terrifying the damage. Keep exploring
