Put together for a friend. Uses only Commons and Uncommons. Also no Campaign cards. In MTG they call it SilverBlack. In Eternal, GreenBlack seems to make more sense as a name.
Anyway, I think this performs about as well as you could reasonably hope from a Rare-less deck, and it upgrades to the Tier 1 Skycraggro deck pretty cleanly. If you stumble across this and wanna upgrade it, absolutely start by adding
Champion of Furys and removing
Skycrag Strangers until you have a full playset of Champions. Then start replacing the
Ruination Sledges,
Twinbarrels, and two of the
Ornate Katanas with
Longbarrels and
Shogun's Scepters until you have 4x of each. All the
Ruthless Strangers should be replaced with
Pyroknights. Then, it's time to get a playset of
Ixtun Merchants, move
Rally to the Market, and get rid of the
Rockslides. (Other decks can give a better idea of a good market, for example my own
Skycrag for the Woman on a Budget.) The last thing I'd put on the priority list is replacing the
Thunderbirds with
Vadius, Clan Fathers; as huge as that upgrade is, it's also the most expensive one, and it's better to strengthen the foundation before that.
For the record, though, I make no guarantee about your ladder success with this deck until you've got some Rares in there.
