A decks I've had some luck with using some odd cards. Thanks to the Gunslinger tribal, the
Hideout Pistol and
Showdown pull double duty whenever played. The removal spells are mostly fast, as it lets you play them on your opponents turn, conserving your power for your turn. It performs well against other midrange decks and decks that rely on burn or Deadly blockers, as just about everything has Quickdraw and can get Deadly. The prevalence of Warcry also helps buff the power of cards drawn later. Possible variations could:
-Dump Ashara for more low range aggro, but there are not any worthwhile 1 cost gunslingers.
-Vanquish could be swapped for Slay, but I prefer the mono color, low cost option and there isn't much you want kill spells for that has less than 4 attack.
-Overwhelm weapons/Spells combo nicely with the sudden double damage Showdown gives, but they'd likely have to replace Inquistor's blade, and the utility of flying is just too nice.
