I was thinking about it and I'm fairly certain that a majority of synergies just involve holding enemies still for allies to land skills.
What are the champion synergies other than this? I'm curious about existing mechanics and if there might be room for more interesting mechanics and synergies in future champions or reworks.
DrCyanide2 votesBraum Passive plus Lucian Passive work together to hold the enemy still.
Morgana Spell Shield plus a Diver or Assassin like Yi or Katarina works well, because it keeps their damage going.
Lulu works well with high attack speed champions like Kog'Maw because of her ability that attacks when they attack.
Xerath works great with a Juggernaut front line, being able to land ult after ult as they're trying to run from the Juggernaut.
There's the Ryze and Nunu ult combo, delivering the full channel into a fight.
Cyber HeroXL1 votesgalio works pretty well with most divers, even if the diver misses by a bit he still allowed the galio to land a good ult.
Jbels1 votesCassiopea's Q benefits from Teemo's toxic shot poison. Although this is most likely due to the fact that the code that works under the hood of Teemo's poison is the same as the code for Cassiopea's abilities, not because it was some kind of intended interaction

LightIsMyPath1 votesIvern can allow melee allies to get in range, his bushes interact with rengo, teemo and cait passives. Sejuani has her melee allies stacking her E. Lulu has great synergy with every ally reliant on attack speed. Braum has his allies stacking his passive Orianna has synergy with whoever can gapclose on enemies to help her land her spells (still not a "hold them still mechanic) Janna synergies with every AD ally
Sure there are more but right now these came to mind
