Basically list the effect from a champions passive, and guess who it is. Then keep the list going by adding your own. I'll start.
Critical strikes and Q hits apply a DoT.
return mana everytime he kills a unit
This Hotrod refunds mana per auto attack based on damage dealt!
This champ has a passive that has absolutely zero effect once it gets to late-game!
This could be a lot of things but I'm ganna go with Garen.
This champion's passive grants health after they kill a unit.
Trundle? Though I think he gains health when any unit near him dies, even if he didn't kill it.
Or it could be Cho'Gath who regains health and mana on kills.
And not Teemo or Garen for mine; those guys still can use their passives.
I strike twice every few basic attacks.
