I get this is kind of a noob question, so bear with me. My friend plays a legacy discard deck, and he'll usually dark ritual or something to make me discard 3-5 cards in the first 3 turns, and by turn 5-6 my hand is empty. (More specifically he's running Griselbrand reanimator, so his hand is rarely empty.)
While this might not work against cheap aggro (I regularly win with RDW), I don't see how any other deck can really handle this. When he has a full hand and I'm limited to 1 new card per turn, which I have to either cast or lose thanks to specters, how am I supposed to ever catch up?
Yet at the same time I know discard isn't like auto-tournie-win, so I'm just not sure how people deal with it.
To give some info about my specific situation and the key cards I use, I am playing:
Legacy combo elves (Elfdrazi) with Priest of Titania / Rofellos, Llanowar Emissary / Ezuri, Renegade Leader / Llanowar Elves / Emrakul, the Aeons Torn / Seeker of Skybreak / Elvish Piper / Fierce Empath / Concordant Crossroads / a bunch of tutors / Vitalize.
My friend is primarily using Griselbrand Reanimator, using Griselbrand / Buried Alive / Animate Dead / Zombify / Dark Ritual / Cabal Ritual / Dark Petition / a bunch of tutors / Crypt Ghast and the death knell being Mind Twist (discard my whole hand) and Infest (kills all creatures in both my decks). On paper he wins using Sorin's Vengeance, Debt to the Deathless, Consume Spirit, and Exsanguinate, but Mind Twist is really what does it.
