Ulgeroth, Roaming Genesis

Ulgeroth's power and toughness are equal to the
number of permanents you control.

When Ulgeroth attacks, reveal the top seven cards
of your library. Choose one, then shuffle —
• Put each land card revealed this way onto the
battlefield tapped.
• Put up to one nonland permanent card revealed
this way into your hand.

"In a barren wasteland, life walked."
