Deck of Illusions

This box contains a set of parchment cards. A
full deck has 34 cards. A deck found as treasure
is usually missing 1d20-1 cards.
The magic of the deck functions only if cards are
drawn at random (you can use an altered deck of
playing cards to simulate the deck). You can use
an action to draw a card at random from the deck
and throw it to the ground at a point within...
