To add another bit of feedback - it seems like a lot of people in the comments don't understand the value of variations so OP you'll want to show an actual case study example immediately.

Here is one to demonstrate:

  Variation 1:
  This famous escape-artist was born in 1874 and died in 1926.

  Variation 2:
  What famous magician born in 1874 passed away of peritonitis 52 years later?

  Answer: Harry Houdini   

Answering any variation causes the next review time for THIS CONSOLIDATED CARD to get pushed back.

I achieve a similar variation system in my own flashcards but use javascript + Anki to accomplish it.
