Budget Skycraggro

Fantastic deck for beginners. Relatively cheap, though requires 4x Champion of Fury to be playable. Heavily inspired from ManuS' Skycraggo

Strategy: Keep it simple. Play one drops on curve and overwhelm opponent with as much damage as fast as possible. Keep torches and perma late game for stronger units. You also always want to attack with your units - you rarely ever have to worry about blocking as you usually outdamage opponents early on.

Core cards
Champion of Fury: Most important card in deck. Fantastic for quick damage and just great overall.
Ankle Cutter: Without him we lose to Titan and Varra every time. Must have 4x imo.
Oni Ronin, Rakano Outlaw: -Warcry buffs are so good early on. A buffed Champion of Fury ends games in a few turns.
Dusk Raider: While a little slow, if you draw a champion of fury with berserk and board is empty, you will get incredible amounts of damage off. Also great for your warcry units a d really any units. The nightfall is also really helpful in terms of providing you with an extra card, which is a godsend for aggro.

Card Explanations
Mischief Yeti: A cheaper version of Pyroknight. While it doesn't have the late game mana sink or overwhelm, it is still fantastic value and synergizes great with the 6 weapons and 4 buff spells in the deck. With this around I honestly wouldn't even bother crafting Pyroknight
Ornate Katana: Honestly just a cheaper version of Longbarrel. If you have that, use it instead. Notably synergies with Dusk Raider though.
Smith's Hammer: A much, much worse Shogun's Scepter. If you have that, play that instead.
Snowfort Trumpeter: A filler card really. Any 2 or three drop that you think is better can go there.
Granite Acolyte: Another filler. Synergies great with Mischief Yeti though.

Upgrades
IXTUN MERCHANT. While some deny the importance of a market in skyaggro, I personally believe that a market is incredible for aggro. This card allows you to get rid of an extra power (you only need 3) and get a much better card instead. Craft 4 of them and put em in place of the snowfort trumpeter and the granite acolyte. Fixes many of the inconsistencies with Skycraggro. Market: Up to you, but I really like warhelm. So neat for bursting the following turn (play a unit, play warhelm, attack with merch + unit). My market: Warhelm, Ankle Cutter, Censari Brigade (underwhelming in main deck in my experience), Cloud of Ashes, and Obliterate. Notable options: Unexpected Results allows you to counter harsh rule or hailstorm.
Vadius, Clan Father: Wouldn't be skycraggro without him. Really solid card, but I recommend crafting the merchant and Shogun's Scepter before him. If you have him, take out one ankle cutter (you have one in market), a dusk raider, and a permafrost and slap 4 of him on the deck.
Shogun's Scepter: So much value. Craft 4 of it and replace em with Smith's Hammer and 2 ornate Katana.
Longbarrel: Craft 2 and sub for Katana.
Pyroknight: Kind of unnecessary as Mischief Yeti does a more than a fine job, but if you really have extra shiftstone, I guess you can craft 4 of them and sub em for the Mischief Yetis. If you already have Pyroknight then definitely play it over Yeti.
