This is a variation based of Kaelos' extreme budget deck for Feln. It utilizes control to kill of anything the opponent drops, including through the combination of madness+devour to take out heavies. Board wipes via hailstorm to deal with aggro, and recursion and card draw via Gorgon Fanatic and Acquisitive Crow.
The main reason to play this deck is because you think it's hilarious to one-shot people with a respawning crow that draws a million of one-drop spells. When you win a match against a relic-heavy deck because your crow drew Bore and in one turn you killed 8 relics, you'll go "WOW. THIS IS SO JANK. I LOVE IT."
The best combo I've seen so far is to get a Lehtrai Falchion onto a Crow that has been brought back with haunting scream for charge+dark return for +1, +1. You can one shot if your Crow generates an additional damage boost, such as Finest Hour, and easily swing your life total massively in your favor.
This deck is also very good at Gauntlet; I am currently on a 7 win streak in Masters. The A.I. is not intelligent enough to deal with the deadly merchants, the lifesteal panthers, and board wipes. Additionally, many of the bosses bonuses end up helping you out!
Give it a try if you want to have some fun with Acquisitive Crow!
