When a format’s depth changes, as Extended did, there will be price movements. It would be profitable to understnad the forces that effect those prices. Remember, no one has won a nobel prize for economics by charting the entire MTG economy, so we’re all just in Best Guess Land. I haven’t the time, sadly, to crunch hundreds of numbers, but my theories generally have some support behind them. Thus, others who wish to attempt to prove or disprove them are welcome, because either way I learn more about how the market works.

There’s really no need to sling any accusations at my qualifications. They speak for themselves. I treat the process of fully understanding these markets much the same way that a scientist researches a problem. Until there’s tons of data supporting the theory, it’s just a theory. Rather than guess at prices, I’d like to know exactly how a rotation tends to influence prices, and when. Just some things to consider before you start wondering “who writes this crap”.

Does this only apply to cards in real life, or do the MTGO cards get affected by this as well? Sometimes the card prices differ vastly between online and paper cards. Any tips on predicting which ones will be worth picking up?
