+1: Venture into the dungeon. (Enter the first room
or advance to the next room.)

-2: Look at the top six cards of your library. You may
reveal a creature card from among them and put it into
your hand. If it's legendary, you gain 3 life. Put the rest
on the bottom of your library in a random order.

-7: You get an emblem with "Creatures you control
have trample, haste and get +2/+2 for each
differently named dungeon you've completed."
