So i need to talk about this deck and why it is what it is. Back during Khans of Tarkir standard I ran a deck fairly similar to this. It was a good deck for what it did and I attempted a version in modern. My problem was that is a heavy 1 mana cost removal format like modern it couldn't survive well enough. When Pioneer was announced my mind came back to this deck and how it worked. So I took an attempt to rebuild it but splashing into white.
The deck is as straight forwards as you can get.
Turn 1 - drop a one drop, preferably a swiftspear if you got one.
Turn 2 - drop a one drop and attach an enchantment, preferably a hammerhand or cartouche of zeal.
turn 3 - buff a creature, preferably a heroic one, and then use one of the double strike spells to deal lethal damage.
It's not exactly complicated. There is an inherent weakness that comes with a deck like this but that's what the sideboard is for. God's willing offers protection as does boros charm against destruction spells and board wipes. Dec in stone and chained makes for better removal around hard to deal with threats and skull crack deals with life gain decks. Often you only need turn 4 at most to make it work. You can win on turn 3 with the deck and it's somewhat reliable in that regards.
The optimal turn 3 win goes as such.
Turn 1 - Swiftspear (1 damage)
Turn 2 - Favored Hoplite/Satyr Hoplite attaching Hammerhand/cartouche of zeal triggering prowess on swift spear (5 damage)
Turn 3 - titan's strength/integrity adding battle rage/boros charm (17/18 damage with trample) or any cartouche/hammerhand (14 damage)
And that is the jist of the deck. When using during khans standard i did beat many a control and abzan midrange deck with this one.
