You can build and test decks. You can draft. You can practice sealed. You can even see other decks that are being built and work from those. This is a great app for mtg players and is continually being improved.
* Build constructed decks
* Practice draft and sealed with the latest sets from MTG
* Pick cards from an mtg booster in a visual layout
* Build your deck with a great interface
* Test your deck after building it
Magic Drafter is always updated to have the latest set of Magic Cards within 1 or 2 days after a new set is spoiled so you always have the latest cards to use.
