Trash Star of Trash Island

When Trash Star. of Trash Island enters the battlefield, exile all other permanents. Each player
puts permanents they control exiled this way into
a pile face down and shuffles it. As long as
a player has cards in this pile, whenever they
would draw a card, they draw the top card of this
pile instead. They may play it without paying its
mana cost.
At the beginning of your upkeep, draw a card.
