Death's Shadow produced a clean break -- including both Grand Prix and team event wins -- and is probably the best deck in Modern. Weren't Bannings Supposed to Nerf Death's Shadow?

Just a few weeks ago there were bannings.

Golgari Grave-Troll was there for Dredge. Yes, Dredge would still be viable, but its biggest, burliest, enabler disappeared.

Gitaxian Probe is kinda sorta not a real Magic: The Gathering card. Why does Gitaxian Probe even exist? The banning of this card pushed a pin into the collective bubbles of decks like Infect, Storm, and... Death's Shadow.

Gitaxian Probe had a special place in the old Death's Shadow deck. Sure, the new version still has cards like Mishra's Bauble, but Gitaxian Probe also cost the Death's Shadow deck life (in most cases), (oddly) helping to grow the centerpiece threat.

A More Interactive Death's Shadow Deck

The previous version was mostly an offensive deck. Wild Nacatl or Monastery Swiftspear got the ball rolling; the creatures were much more plentiful... but the interaction was deemphasized.

The current version is almost a Jund deck. This deck has only a few creatures (even if they are doozies)... It has a ton of midrange interaction instead. Fatal Push, a ton of direct hand destruction including the maximum numbers of both Thoughtseize and Inquisition of Kozilek, and even Tarfire have repositioned the archetype.

Tarfire?

In addition to having the superpower of being one mana, Tarfire is a Tribal Instant. As such, it's really useful for 1) buffing Tarmogoyf, and 2) getting Traverse the Ulvenwald online super quickly. Some versions even have Seal of Fire to make Tarmogoyf that much bigger!

Survival

Most of the offense in this strategy is accomplished by only two creatures: Death's Shadow and Tarmogoyf. Unfortunately -- and especially given the printing of Fatal Push -- neither of those guys is hard to kill. The deck can weather opposing removal in a number of ways...

• Liliana, the Last Hope - Played in some versions (over Liliana of the Veil), Liliana can put a creature from your graveyard back in your hand.
• Renegade Rallier - Played in some versions (over Ghor-Clan Rampager), this creature can recycle cheap creatures
• Kolaghan's Command - Played in essentially every version, Kolaghan's Command is a multi-pronged tool. It can lock opponents out, it can do the last two points, and of course it can raise the dead.

Thirteen creatures have never stretched so far.
