Unnatural Pinnacle

You start the Game with Prismatic Tower
and a random Pinnacle-spell in your
Command Zone.

During your end step, sacrifice a creature.
Then reveal cards from your library until you reveal a creature with the sacrificed creatures' plus 1. Put that creature into play.

At the beginning of your Upkeep, if you have
the 5 creatures with the highest mana value in play, you win the game.
