The Lost Caverns of Ixalan

Abuelo's Awakening | Sorcery | | Return target artifact or non-Aura enchantment card from your graveyard to the battlefield with X additional +1/+1 counters on it. It's a 1/1 Spirit creature with flying in addition to its other types. | Eelis Kyttanen

Terror Tide | Sorcery | | Fathomless descent — All creatures get -X/-X until end of turn, where X is the number of permanent cards in your graveyard. | Brock Grossman

Hit the Mother Lode | Sorcery | | Discover 10. If the discovered card's mana value is less than 10, create a number of tapped Treasure tokens equal to the difference. (To discover 10, exile cards from the top of your library until you exile a nonland card with mana value 10 or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.) | Diego Gisbert

Cosmium Confluence | Sorcery | | Choose three. You may choose the same mode more than once. • Search your library for a Cave card, put it onto the battlefield tapped, then shuffle. • Put three +1/+1 counters on a Cave you control. It becomes a 0/0 Elemental creature with haste. It's still a land. • Destroy target enchantment. | Kasia 'Kafis' Zielińska

Wail of the Forgotten | Sorcery | | Descend 8 — Choose one. If there are eight or more permanent cards in your graveyard as you cast this spell, choose one or more instead. • Return target nonland permanent to its owner's hand. • Target opponent discards a card. • Look at the top three cards of your library. Put one of them into your hand and the rest into your graveyard. | Ryan Valle

Molten Collapse | Sorcery | | Choose one. If you descended this turn, you may choose both instead. (You descended if a permanent card was put into your graveyard from anywhere.) • Destroy target creature or planeswalker. • Destroy target noncreature, nonland permanent with mana value 1 or less. | Kasia 'Kafis' Zielińska

Squirming Emergence | Sorcery | | Fathomless descent — Return to the battlefield target nonland permanent card in your graveyard with mana value less than or equal to the number of permanent cards in your graveyard. | Simon Dominic
