Crucible of Worlds

Search target opponent's library for a creature card and put that card onto the battlefield under your control. Then that player shuffles.

At the beginning of your upkeep, if this creature is in your graveyard, you may pay 2G. If you do, return target creature card from your graveyard to your hand.

Destroy target permanent.

Each player may put an artifact, creature, enchantment, or land card from their hand onto the battlefield.

Destroy all creatures target opponent controls. Draw a card for each creature destroyed this way.

When this creature enters, search your library for a creature card with power 2 or less, reveal it, put it into your hand, then shuffle.

Exile target creature. Its controller gains life equal to its power.
