Mardu Lifer (Standard)

Mission:
Maintain tempo lead through Lifelink.
Keep the board clear with removal.
Finish off with hasty fliers.

Tools:
Spells are heavy on removal to keep the board clear and to protect threats. These removal spells trigger lifelink from Seekers and Examplars for a huge tempo swing to the face (6 point gap or 8 point gap). Did not opt for Sorin, because at turn 4 I want a threat on the board, instead of just an enabler.

Rabblemaster hits hard on its own, and a couple dragon fodder tokens make it hit even harder. All these goblins build up nicely for more lifelink food for Butcher, who swings for 10 point gap in the air.

Mid-game (turn 5+) is all about finishing off the opponent with hasty fliers. 2 Sarkhans instead of a full playset of Stormbreaths, because he can trigger lifelink and provide additional removal when playing from behind. Also, Stormbreath is the only creature that cannot be protected with Valorous Stance.

Card draw is supplied by read the bones instead of outpost siege, because the 4 drop slot is filled with threats. Spending life points shouldn't be a problem with this deck, especially since the card itself triggers lifelink.

The top-end threats in this deck such as Ojutai Examplars that can dominate the mid-game in a removal heavy shell like this deck, but Languish might warp the format enough for 5 toughness creatures such as Priest of the Blood Rite to be considered, of which the priest himself can be sacrificed by Butcher.

A single duress with another one in the sideboard can prove very useful against control decks that disrupts the tempo of this deck. More important than thoughtseize or despise due to the heavy removal package already in this deck.

Final note: I believe that this setup is more consistent than the Thunderbreak + Draconic Roar combo, because my every card in this deck has great synergy with each other, instead of just 20% of it. Please try it out and let me know what you think.
