Mnemonic Betrayal | Sorcery | | Exile all opponents' graveyards. You may cast spells from among those cards this turn, and you may spend mana as though it were mana of any type to cast those spells. At the beginning of the next end step, if any of those cards remain exiled, return them to their owners' graveyards. Exile Mnemonic Betrayal. | Clint Cearley

Notion Rain | Sorcery | | Surveil 2, then draw two cards. Notion Rain deals 2 damage to you. (To 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.) | Lius Lasahido

Unmoored Ego | Sorcery | | Choose a card name. Search target opponent's graveyard, hand, and library for up to four cards with that name and exile them. That player shuffles, then draws a card for each card exiled from their hand this way. | Volkan Baǵa

Beacon Bolt | Sorcery | | Beacon Bolt deals damage to target creature equal to the total number of instant and sorcery cards you own in exile and in your graveyard. Jump-start (You may cast this card from your graveyard by discarding a card in addition to paying its other costs. Then exile this card.) | Titus Lunter
