Magic's Event Decks are somewhat like Yugioh's Pre-constructed decks. (Priced SGD$45.90 at Comics Connection) I found out about them quite late and they seem to be pretty competitive out of the box unlike Yugioh. They give the max copies of quite a number of cards (the common rarity ones), about 2 each of the uncommon-s and 1 each of the rare-s, compared to Yugioh's 1 each of most of the cards. To do a little better, you might need to buy up to 2 to get the max copies of the uncommon cards.
For Innistrad set's 2 Event Decks, they are themed around White Weennies, called "Hold the Line" and a Graveyard-based deck, similar theme to Lightsworns, Deathfed. (Magic also has a Flashback spell card mechanic that enables casting of these spells from graveyard which makes it better than Lightsworns) I think White Weenies are pretty straightforward and this deck-type has been around since over 15 years ago when I was playing Magic. The Graveyard-based deck needs a bit of setup and I personally think you should get more fun playing it, out of the two.
