Cheap version which I've just hit Master with in my second month of playing.
Replaces the standard 4 Vadius with 2 Thunderbird (Flying, Aegis) and 2 Censari Brigand (Charge, Double Damage vs players) both can often get an attack in before dying, and generally the deck has a few Aegis and Charge for the same reason including playing around Harsh Rule.
Pretty simple, attack all the time, torch weaker enemies and save permafrost for stronger ones. Longbarrel almost always worth saving and playing Piercing Shot. Shugo Standard normally worth holding on for Shugo Tactic.
Merchants almost always go for Overwhelm, although Flamestoker can be good if drawn late or against other aggro or sometimes control decks. Skycrag Banner has got me out of a few fixes, Cloud of Ash once or twice but don't think I've ever used Rally (usually trade so rarely enough units to make worthwhile) so there may be a better match.
