Ancestors' Faces

Whenever you complete a dungeon, you gain 2
life, then reveal the top X cards from your
library, where X is equal to the amount of life you
gained this turn. Put all land cards revealed this
way into your hand, and the rest on the bottom
of your library in a random order.

When chaos ensues, you venture into the dungeon
three times. (Enter the first room or advance to the
next room. Repeat this process two more times.)
