Zilean + Ultimate Revolution
A Tier Combo
Zilean R on himself: while waiting to revive, Ultimate Revolution treats him as already revived, immediately refreshing R. Cast it in time and you can perma-revive yourself, untouchable. R-on-self is mandatory to keep the loop; extra ability haste goes into Q poke.

Malphite S Double nuke. 
Karthus S Ultimate Revolution makes Karthus game-warping with near-constant double-ult windows. 
Sion S Sion's R code conflicts with Ultimate Revolution: after casting R, he's CC-immune for the rest of that life — even his zombie state stays immune. Pair with crit items and dive freely. Cast R early to lock in the permanent CC-immunity buff, then go ham. 
Ashe S Ult has high AP scaling and deals magic damage. 
Hecarim S Crit chance + Death's Dance — abilities grant shields based on crit, while Death's Dance converts 30% damage into bleed that the shields absorb. Keep ability frequency high and you maintain a permanent 30% damage reduction. Karthus S Ultimate Revolution bug is patched (no more 4 R's), but you still get one R per life — pair with the suicide build for monster output. This style doesn't need Plague's ult haste — build pure magic pen / AP for max R damage. Strongly recommend Final City Transit synergy. Malphite S Use hexes to slash R's CD. Take any R-CDR hex; Ultimate Revolution is even better. 
Ekko S High damage, good tolerance, long R cooldown. Keep exploring
