* Use the new, shortest API m=
* for a card, grab prices for all sets
* use the lower price for a card from all sets, but avoid prices=0
(e.g.: some M15 cards have no price yet)
Query card database to get a multiverseis for a card.
Get card price using that id instead of card name.
Tested Aether, split cards, question elemental?, _____
* the previous PriceUpdater class has become abstract
* BLPPriceUpdater inherits the old code for blacklotusproject.com
* DBPriceUpdater is a new implementation for deckbrew.com
* add a setting to choose between the two
"The price tag feature currently has two bugs.
1. The final price that a card ends up with is the one in the last set
alphabetically, instead of the one from the set with the lowest price.
2. Black Lotus Project sometimes gets in prices for cards from Masters
Edition, for some reason. This set only exists in Magic the Gathering:
Online, i.e., not physically, and should not be considered. This might
be considered a BLP bug and not a Cockatrice bug.
This patch fixes those two bugs. I also changed the price value to be
based on BLP's "price" value instead of the "average" value. Seems more
logical."
