It's a little expensive, and not great at destroying non-artifacts, but the life gain helps make up for those things
The card pool often includes a card from the first set of a new era, but not all eras are represented this way
Apart from the new partner commanders and the four-color face card, you get two Esper commanders, a Boros commander, a UW Commander, and two mono-red commanders, all of which deal (at least, to some extent) with the artifact theme of the deck
Card translations comes again from ToineLay, thank you
Its still worth it because of the sheer number of cards it lets you draw
For me the reason I love this game so much is that its every bit as good playing solo as it is playing in a group
