Hey, I am new to Vintage and have been composing deck ideas. I am a fairly competitive Modern and EDH player, however since I am unfamiliar with a lot of Vintage cards and strategies I am at a disadvantage. I wanted to compose a Green and Black deck as those are my favorite colors to run. The idea of a discard deck seemed fun, but wasn't sure if that was a bad idea in the format. Feel free to educate me.
Welcome to Vintage! My first deck in the format was GB Dark Times, a Dark Depths list that used Dark Confidant for Card Advantage, disruption in the form of Discard, Leyline of the Void, etc and a quick kill with either Hexmage or now Thespians Stage, and Helm of Obedience to combo with Leyline of the Void. I'm not sure how viable the deck would be nowadays but you could certainly try it out. If you would like any assistance brewing up a list I'll gladly contribute.
