Search your library for two basic land cards, reveal them, put them into your hand, then shuffle. (Then exile this card. You may cast the creature later from exile.)

Reveal the top four cards of your library. You may put a permanent card revealed this way with mana value less than the greatest mana value among permanents you control onto the battlefield. Put the rest on the bottom of your library in a random order.

Prevent all combat damage that would be dealt this turn. You get a glory counter. (You lose glory counters before life. A player with ten or more glory counters wins the game.)
