Just posting this due to a Facebook discussion. I used this deck to get to masters last month and it's pretty fun.
The general strategy is to use your cards fast and try to drop a Fire Sale, then Equalize, then Inferno Den/Pyro.
To get there I use a lot of removals (Smite, Just Des, Defiance) and stallers (Clergy, Kemmo) and the rock star is Raging Firemaw. That card is very difficult for opponents since it can block and also attack even if stunned. Amilli is there mostly to be annoying and defend Den if you get it.
But you drop a Den after a Fire Sale and you can do 50+ dmg the next turn, it's crazy. If you get to 18 power, Pyro wins the game instantly. Also if you have up a commando for the Den, it buffs all the minions, haha, ouch.
The big trick is learning when to trigger fire sale - you drop it without a way to clean up their "big turn" you can lose the game instantly. And sometimes you just have to deal with them getting a ping on scorpion trap and the ONE card they had in hand was witching hour... lol, ow. If you have equalize you can wipe their entire board after dropping a den and also clean out their hand... that's the dream.
Bore is very, very, very strong. I had it in the market for a while but just needed it like ALL the time. I have had games where I used Bore 3 times and still lost (omg at some of the relic deck), but usually, it wrecks the build you are facing unless they get an incredible draw. Bore can burn their aegis, THEN take out their relics... love it.
And, always remember, rng is real - you can win a game super fast, but also get suck on 2 power for 8 turns ... just take that with a grain of salt. I try to accept those, but the ones that bug me are when you HAVE 20+ cards that can win it and can't draw any of them for 5 turns... arg.
NOTE: I don't netdeck so this is all my stuff, and I'm 100% sure better players can turn this into a "real" deck ;)
