Enchant creature
When Disturbing Conversion enters the battlefield, each player mills two cards.
Enchanted creature gets -X/-0, where X is the number of cards in its controller's graveyard.
Enchanted creature gets -4/-4.
When enchanted creature dies, surveil 2. (Look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.)
Choose target creature you control. Each other creature becomes a copy of that creature until end of turn, except it isn't legendary.
Draw two cards. Then you may exile an instant or sorcery card from your hand. If you do, search your hand and library for any number of cards with the same name, exile them, then shuffle. Seek an instant or sorcery card for each card exiled from your hand this way.
