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   

Variations ARE the SAME CARD. They're just a means of "rephrasing" the question to break your brain from its ruthless pattern matching ability.

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.
