I found this decklist while checking the Magic-League websites for Magic: the Gathering Standard decks and this version seem to be more of a straight-forward two colors (Black White) build. The deck was played by username HappyJace and finished first place in the December 5 Standard MtG Trials.
I think he cut off the fetchlands in favor of more mana for a late game huge Secure the Wastes. He also preferred Gideon over the Archangel of Tithes as the planeswalker is more versatile in various situations such as pumping the army with the +1/+1 emblem or just plain Ally token generation to swarm the board.
Here is his version of the deck B/W Strangler:
