Nufi, Master Magician

When Nufi enters the battlefield, choose a player.
As long as Nufi is on the battlefield, the chosen
player draws cards from a deck of playing cards
instead of their library. Number cards are
creatures with mana cost {x} and power and
toughness X/X, where X is their number. Red
and black face cards are mountains and swamps,
respectively. The chosen player may pay 3 life
and discard a playing card to draw a card from
their library.
