Casino of Envy

(As a Palace enters, choose a creature you do not control to attach it to. When that creature leaves the battlefield, exile this card, then cast it transformed.)

When Casino of Envy enters the battlefield, create a Treasure token if an opponent has more lands than you.
You gain 4 life if an opponent has more life than you. Create a 4/4 white Spirit enchantment creature token if an opponent controls more creatures than you. Draw a card if
an opponent has more cards in hand than you.
