Team Composition Ideas

What are your best team compositions that you have used in the past? What are some good team comps that people can use?

A couple of my examples would be: Shen/Pantheon/Azir or Anivia or Lulu/Vayne or Draven or Kogmaw/Janna or Lulu Can siege, split push, or team fight. Basically Protect the ADC with vayne/janna/shen core. Lulu for extra protection or if janna gets banned, Anivia if Azir gets banned. Draven or kogmaw can also be used if vayne gets banned... Although I'm not sure if draven is good for protect the ADC compositions. The preffered composition would involve shen/panth/azir/vayne/janna imo.

Malphite/Vi/Yasuo/Miss Fortune/Janna or Alistar Basic Yasuo Composition.
