If there happens to be a card featuring the keyword dredge among them, you can skip your draw step from here on and dredge cards for the rest of the game to fill the graveyard.


While this doesn't let you discard cards from your hand, it essentially skips the first and complicated part of Dredge's game plan and directly puts five cards from the top of your library into your graveyard. A first list tried to incorporate blue into its mana base to cast on the first turn of the game, targeting the Dredge player itself.
