Demons are scary especially when they grow bigger!
This deck is for fun and has a good winrate against most minion heavy decks. Currently 25-6, this deck loses almost against all rogues and control locks . I know that the winrate could be a lucky streak, but as you can see its working so far. When i posted this deck i haf 15-3 and now 25 - 6. Winrate lowers with ranks ofcourse..
Mulligan for 1 drop demons, Flame Imp Voidwalker Malchezaar's Imp if you have that, you can keep the upgrades or potentially a Vulgar Homunculus. You will have a hard time winning without your one drops as you want these to grow BIG.
The key component is to get your early minions big as fast as you can and hit face as often as you can. your doomguards/soulfire can finish it off. The deck has quite some taunts, which helps to guard your bigger/buffed demons. DO NOT just go for board control, as only early they can't do e.g. dragon fire etc.. know when you are ahead and pwn that face ya!!! typically only 8 turns needed, though i choose to have Bloodreaver Gul'dan as potential finisher at 10 (respawn the doom guards). In addition i added silence cards Spellbreaker so you can silence their taunts and continue to bring them low.
- Mulligan for 1 drop demons
- Make them bigger and hit face with it.
- Protect them (e.g. against priest try to buff to 4 attack) and play taunts (keep hitting face with demons)
- Lower them fast with doomguards and soulfire. Getting them in kill range.
- Win at turn per average at turn 8.
---- update ----
Winrate lowers, mostly due to many warlocks/hunters and some bad draws, still 75%. with 43 wins 14 losses
Check out this video. he plays it well! i would be bit more aggresive with the doomguards.
