Overall theme: YOU WANNA GO FAST, this decks goal is aggro, don't worry about losing minions or auras as long as you get value.

Strengths and weaknesses: I've found it goes well against mid-range decks and aggro with small minions, Imperial legion is definitely a weakness I've found against other fire aggro decks specifically.

Opening hand / mulligans: For sites my goal is two air threshold and three fire threshold. Try to mulligan for at least one double or triple site, Smokestacks helps against potential loss of mana from earthquakes moving triple sites or T.C.O.o.S, as well as helping against pebbled paths.

For spells focus on dropping minions and auras on curve. 2,3,4.

Single card discussion The dream combo is to have a four-cost aura on the board played the turn before or more, and Warp spasm, then Shatter Strike. That's potentially 16 damage for 7 mana.

Most importantly have fun! let me know in the comments if you have any improvement suggestions, Thank you!
