Ninefold Gates

Place the first two creature cards that enter your graveyard at the bottom of the graveyard pile and
turn them sideways.

You may not look at cards in your graveyard other

"Nine times the space that measures day and night
To mortal men, he with his horrid crew
Lay vanquished, rolling in the fiery gulf
Confounded though immortal..."
