Dawn of a New Age

As an additional cost to cast Dawn of a New Age,
remove all Genesis counters from permanents
you control.
Put all cards from your hand, battlefield, and graveyard into your library. Search your library for a Zihena Seed of Creation card and two lands and place them onto the battlefield under your control, then shuffle your library. Draw seven cards. Your life total is the number of Genesis counters removed when this card was cast.
