The general gameplan is to combine the better parts of the skycrag aggro early game with midgame threats like Soulfire Drake and Firemaw for more consistent deck.
Updated for The Dusk Road.
Tracker gives free wins against grenadin and the deck is fast enough to go under TJP and Feln, so I think the deck is currently in a very good place as Titan decks are unpopular.
Matchup against pure aggro decks is awesome thanks to permafrost and pings from tracker.
Crystallize is essential in matchups where they can gum up the ground and is excellent at race situations.
It's almost as good here as it is in elysian.
Maybe I could run cloud of ash instead, it's slightly better in titan matchups, but it doesn't have the dual purpose of killing their x/1s.
