The Lost Caverns of Ixalan

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

Glimpse the Core | Sorcery | | Choose one — • Search your library for a basic Forest card, put that card onto the battlefield tapped, then shuffle. • Return target Cave card from your graveyard to the battlefield tapped. | Francisco Miyara

Malamet Battle Glyph | Sorcery | | Choose target creature you control and target creature you don't control. If the creature you control entered the battlefield this turn, put a +1/+1 counter on it. Then those creatures fight each other. | Andrew Mar

Over the Edge | Sorcery | | Choose one — • Destroy target artifact or enchantment. • Target creature you control explores, then it explores again. (Reveal the top card of your library. Put that card into your hand if it's a land. Otherwise, put a +1/+1 counter on that creature, then put the card back or put it into your graveyard. Then repeat this process.) | Ryan Valle

Walk with the Ancestors | Sorcery | | Return up to one target permanent card from your graveyard to your hand. Discover 4. (Exile cards from the top of your library until you exile a nonland card with mana value 4 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.) | Loïc Canavaggia

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
