Wincon's
Death's Shadow: Shadow is the Primary Win Condition of This Deck. As with any Shadow Build the deck is based around making our Shadows very big very fast and quickly destroying our opponent. Shadow can start attacking our opponent as a 5/5 as early at turn 3 making for a very fast and Efficient win. If one of our Early Shadows are Killed you can always use Ranger of Eos to get 2 more.
Gurmag Angler + Tasigur, the Golden Fang: Both Tasigur and Angler are very similar in that they are effectively 1 mana 5/5s. It is important that both of these creatures can be played as early as turn 2 allowing us to quickly pressure our opponent. These 2 cards are our secondary win condition mainly because of their inherently aggressive nature paired along with their great stats.
Liliana of the Veil: Lili is a last resort Win Condition that we only ever rely on when the games is a board stall and we can continue disrupting our opponent with Lili. If Lili is ever your game plan you will tend to be out of gas and in Topdeck mode making her discard ability very effective. If you do get to ultimate Lili it effectively allows you to set your opponent so far back that they will be unable to stop your threats once you get them.
Removal and Discard
One amazing thing about the Mardu version of Death's Shadow is its use of the best spot removal out of all the Shadow Decks.
Path to Exile: Path is probably the only real reason to play White in any Death's Shadow List. Its ability to completely eliminate a threat whether it is a Death's Shadow, Tarmagoyf or even a Griselbrand makes Path effectively the best spot removal in this deck. Yes, it does allow for your Opponent to gain an extra land, however, with the aggressive nature of this deck that land is pretty irrelevant.
Fatal Push: 5 of the most played creatures in modern have 2 similarities. One, they all cost less than 2 mana. Two, Fatal Push kills them. Death's Shadow, Tarmagoyf, Birds of Paradise, Noble Heriarch, and Snapcaster Mage die to Fatal Push. This card is amazing which is part of the reason it's holding at $9 for a mass-produced Uncommon. Crazy.
Dismember: This cards strength in the deck comes with its ability to remove most creatures for the low cost of 1 mana while reducing our Life Totals to make shadow stronger. The card is really good which is why we are running 3 of them. Note: You can cast it for 1, 2, or 3 Mana depending on your Life Total and the current board state. Never take Life if you are feeling in a very bad position.
Lightning Bolt: 1 Mana 3 Damage. Enough said. In some cases, you can even Bolt yourself to make your Shadows Stronger.
Kolaghan's Command: Kommand is amazing. Its ability to bring back and creature from our Graveyard is really helpful against removal Heavy decks. In addition, it kills Artifacts. Chalice of the Void stopping you from playing 1 drops. Destroy it. Aether Vial is making your opponent's deck too fast. Destroy it. It's situational flexibility makes this card one of the best spells in the deck.
Thoughtseize: The ability to forcefully remove cards from an opponent's hand is amazing. The knowledge you get from looking at their hand also Amazing. The low cost of 1 mana makes this card perfect. While there is the Downside of the Life loss, our deck wants and needs that Life loss to happen. Seize may be the best and most consistent card in this deck.
Life Loss
Really the main way we lose life in this deck is through the cracking of fetch-lands for shock-lands. However, we do have 4 copies of Street Wraith for some added life loss.
