Depends what you're looking for.
There's very little deck customization. Each deck starts with 60 cards and you unlock a few each time you win with that deck. It leaves you with about 75 cards to build a 60 card deck out of. Each deck is independent from each other -- you can't use cards from the mono-blue deck in the green/blue deck (unless WotC themselves decided to put the card in both decks).
It's basically a gateway into playing real Magic. You get to try a handful of deck archetypes and see if you like the gameplay for $10-15, and if you do and want to play, you end up buying real cards.
