Hi Insiders! As part of compiling our OGW cheatsheet, I also did a bit of feeble Excel wizardry to see what cards in BFZ gained and lost value since the prerelease. Shocking nobody, the prices fell a lot; this is typical in any set, by the way. Here's the data on the set.
What were the big gainers? Here they are:
|19.40%||Ulamog, the Ceaseless Hunger|
Every other card in the set lost value. What were the biggest losers? Well, I hope you didn't park your money in these cards, because some of them would have eradicated your bankroll.
|-74.10%||Greenwarden of Murasa|
|-74.81%||Noyan Dar, Roil Shaper|
|-85.32%||Sire of Stagnation|
|-89.16%||Bring to Light|
That's right--if you got Bring to Light at the prerelease, you would have lost almost 90% of the value of the card.
In general though, the set didn't lose a staggering amount. If you bought one of every card worth over $1 at the time of the Prerelease, you would be out 33.9% of your investment. If you lost less than that, you beat the average.
If you want to play more with the Excel spreadsheet, I uploaded it here for ya.
