I read one of your posts stating that they only need the time stone to undo what Thanos done....... but thats not true. All of the stones would be required to undo what has been done as all of them were needed to do it.
each stone amplifies the power of the others, so when put together they literally have infinite power. without reading the comics I wouldnt know that. Some things are constant throughout all Marvel Universes..... so comics readers have a much better idea of where the story will be going(without knowing the exact details)
