You're always welcome to just show up and play regardless
You pay all costs and follow all timing rules for cards played from exile using The Legend of Roku's first chapter ability
(To manifest dread, look at the top two cards of your library, then put one onto the battlefield face down as a 2/2 creature and the other into your graveyard
Neither way works to push your creature's triggers (whatever they may be), so they really only work in ramp-esque builds, which limits their usefulness
From then on, youre in charge who deals combat damage, letting you shut down those aggressive Krenko, Mob Boss decks while you and your newfound allies dig for answers
But again, this distribution makes it so the odds of any particular card even being opened at a draft are low
