The core concept of this deck is simple: go wide and play a
Edge of Uprising or
The Throne Room to take advantage of it.
Kindling Carver is a source of continuous card advantage, turning outclassed or useless units into new cards at a low cost.
Now, to address the obvious question: why no
Jekk, Mercenary Hunter? A couple reasons. 1) We want to be able to play
Mother of Skies and
Mobilization, so the power distribution would be nearly impossible. 2) The most played decks right now are full of units that don't care as much about Jekk, either going positive in tempo or being too big for it, and then he just ends up outclassed on the board. Instead, we play
Kenna, Uncontained in a similar role: able to act as removal with a body and provide some incremental advantage as the game goes on, but having evasion and being easier to play.
In playing this deck, you generally want to keep hands that have at least one "army in a can" effect. On top of that, there generally needs to be at least one payoff card or else a
Wisdom of the Elders to get you to a payoff.
Mother of Skies can be both, but only if your units include producers of multifaction units. Be careful not to overcommit - the most common [/card]Blazing Salvo[/card] targets are the counterspells to avoid board wipes or similar.
The other big omission is
Primal Etchings. The reason for this is that most of the things it would grab from the market can be fulfilled using
Blazing Salvo, and the early removal can be critical in some matchups. Etchings is just too much of a tempo hit for us to be getting max value out of it. I will admit that the market is still a bit of a work-in-progress to figure out which effects matter the most to have.
Updated to be more aggressive - this version took me into the top 100 in expedition.
