Karthus S Infinite Recursion lets Karthus cycle Requiem absurdly fast and constantly pressure team HP bars. 
Lux S Pure AP is squishy and damage-light — go half-tank and stack CDR for faster passive procs. Use R to clear waves. 
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. 
Zed S Ethereal Weapon makes abilities trigger item effects — feels like old-school Zed. 
Ezreal S Ezreal's passive at max stacks gives 50% attack speed, which Purist + Caster converts to 200+ ability haste. Q's hit-reduces-CD means Q has practically no cooldown late, and R refreshes in under 10s. Late, full-screen ult every 10 seconds = enormous pressure. Keep exploring
