Every upkeep, you get a free impulsive draw (exiling cards off the top of your library and being able to play them that turn), but then, for each land card you exile, you get a 3/1 dinosaur token, and for each nonland card you exile, you get a Treasure token
Each blemish or mark against the integrity of the card knocks it further down the scale
When you warp a card into play, you get to keep it until the end of your turn, when you exile it
