Manifest Dread | Sorcery | | Manifest dread. (Look at the top two cards of your library. Put one onto the battlefield face down as a 2/2 creature and the other into your graveyard. Turn it face up any time for its mana cost if it's a creature card.) | Andrey Kuzinskiy

Monstrous Emergence | Sorcery | | As an additional cost to cast this spell, choose a creature you control or reveal a creature card from your hand. Monstrous Emergence deals damage equal to the power of the creature you chose or the card you revealed to target creature. | Loïc Canavaggia

Say Its Name | Sorcery | | Mill three cards. Then you may return a creature or land card from your graveyard to your hand. Exile this card and two other cards named Say Its Name from your graveyard: Search your graveyard, hand, and/or library for a card named Altanak, the Thrice-Called and put it onto the battlefield. If you search your library this way, shuffle. Activate only as a sorcery. | Sam Wolfe Connelly

Wary Watchdog | Creature | Dog | When Wary Watchdog enters or dies, surveil 1. (Look at the top card of your library. You may put it into your graveyard.) | Olivier Bernard
