Katarina's Passive - Voracity Scoring a kill or assist will reduce all the cooldowns of Katarina's abilities by 15 seconds.

Lee Sin's Q - Sonic Wave Active: Lee Sin shoots a wave of sound in a line, dealing physical damage to the first enemy it hits and revealing the enemy for 3 seconds. If Sonic Wave hits, Lee Sin can cast Resonating Strike within the next 3 seconds. Active: Lee Sin dashes to the enemy revealed by Sonic Wave, dealing physical damage including 8% of the target's missing health. Minions and monsters take a maximum of 400 damage

Garen's W - Courage Passive: Garen's bonus armor and magic resistance are increased by 20%. Active: Garen gains a defensive shield for a few seconds, reducing incoming damage by 30% and granting 30% crowd control reduction.

Sion's E - Enrage Toggle: While toggled on, Sion has increased attack damage at the cost of some health for each autoattack. While Enrage is active, Sion permanently increases his maximum health whenever he kills a unit with either his attacks or abilities. This effect is doubled against champions and large units.

Tryndameres R - Undying Rage Active: Tryndamere instantly receives Fury and becomes immune to death for 5 seconds during which his health cannot go below 1 health. This move is usable even when stunned, silenced or suppressed. This ability has a 0.5 second delay before activating.

I was Kinda evrywere with this, I mainly wanted Kats passive and Trynds ult, but I do need some ore abilities. Q is a nice gap closer. W is to get out of CC. E is a damage steroid. R synergises with the passive, 15 sec cooldown on all abilities with a kill or assist.
