Its still worth it because of the sheer number of cards it lets you draw
It's a little expensive, and not great at destroying non-artifacts, but the life gain helps make up for those things
The next two cards are specialthey depict the same scene but from two different perspectives
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
In this way, your deck still functions if you miss a beat while you set up your mana
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
