If you cant do this, youll instead mill the top card of your library
It's great fun in many places too, like control, Curses, Simic Ramp, and more
Rarely do we have an in-game keyword as an article title so for those who arent familiar: milling is the act of taking cards from the top of a library and putting it in the graveyard, and its called mill due to the card Millstone
Jill and Joshua both help out in this regard, with Jill acting as a way to slow down your opponent's onslaught, and Joshua helping you curate your hand by discarding dead cards in a given matchup to find cards that better suit your needs
Theres a reason that this card is THE chase card of the set
