Commander's Arsenal Initial Barrage

Commander is a casual format. It consists of hundred-card decks that can only use one of any card other than basic lands. The format is a fan creation and is still managed by a Rules Committee outside of Wizards of the Coast. You can learn more about this format over at MTGCommander.net or by looking through the Serious Fun archives.
For many Commander players, a new product's release represents an important event. For sets with new and exciting cards it is a time largely to get access to those, such as with Return to Ravnica. For our other products, like the From the Vault series or the upcoming Commander's Arsenal, the excitement is for what we might already have but get in a new form.
So there I was, sitting in the coverage area for the Pro Tour, and while I listened and watched coverage my eyes kept straying to my to-do list item:

Not bad as far as things to do go, especially while watching the best Magic players in the world sling spells.
We haven't said a lot about Commander's Arsenal, but with the release looming in the near future, it's time to pull back the curtain and reveal some of its treasures.

As we've said, after the great reception for the Commander decks last year, Wizards of the Coast plans to support the format with regular releases. We didn't have enough time to create another set of decks for this year, so instead we have this arsenal of weapons.
Rather than giving you all the cards today, we're going to dole them out in batches, some today (obviously), some tomorrow over at MTGCommander.net, and then the full release Thursday (here again). Hope you're ready!
Oversized Cards
To support Commander, we have been putting out oversized cards for commanders. The oversized cards are a fun way to display and easily draw attention to your deck's commander. In the Arsenal, we're releasing ten new oversized cards. We've already revealed

I have a special love for Grimgrin. I was able to preview him for Innistrad and actually shot the video while covering Pro Tour Philadelphia, a fateful event where I would hear word of an open content manager position at Wizards.

While I wasn't able to preview her, Mayael is one of my favorite commanders. I love nothing more than throwing the figurative dice and seeing what big creature sits in my deck's top five cards. My deck uses lots of acceleration to get to Mayael's six mana for activation, usually reaching it on turn four and then just continuing to put fatties on the board.
My top three favorite creatures to flip from Mayael:

The truth is that I don't have a five-color Commander deck. Never built one. I think, though, that when I do, it will be
Regular-Sized Cards
Now, onto the normal-sized cards, and oh boy are they pretty awesome.

Dragonlair Spider—First-Time Premium!
One of the awesome things about this set of cards is that it is going to be the first time a handful of cards are printed as premium foils, such as this one!
I love the flavor of this card—despite being red and green, there is something inherently creepy about it: The more you struggle as you face the spider, the more little spiders come out. I haven't done it yet but once we get a Spider lord I can't wait to make a Spider Commander deck. Maybe I'll call it "Eye Spy-der."

Command Tower—New Art!
Based on the revealed art, this should surprise almost no one, but here is another awesome premium foil. Technically not the first premium version for this card, since there was a promo for our judge community, this will be the first packaged version. It also features the fantastic new artwork, of course.

Regardless, this premium version looks amazing and might be worth throwing in my

Chaos Warp—First-Time Premium!
In Standard and other formats, the graveyard can often be a hindrance for players in terms of accessing cards. In Commander, that restriction is null and void—the graveyard is just another resource to be accessed with the multitude of available recursion spells.

There you go! Eight cards (five normal sized, three oversized) from the upcoming Commander's Arsenal. Be sure to check MTGCommander.net on October 24 at midnight eastern to see the next batch of cards we're revealing from the set! And I'll be back on Thursday with the second part of my update.
