The Lost Caverns of Ixalan

Deeproot Pilgrimage | Enchantment | | Whenever one or more nontoken Merfolk you control become tapped, create a 1/1 blue Merfolk creature token with hexproof. | Rémi Jacquot

Corpses of the Lost | Enchantment | | Skeletons you control get +1/+0 and have haste. When Corpses of the Lost enters the battlefield, create a 2/2 black Skeleton Pirate creature token. At the beginning of your end step, if you descended this turn, you may pay 1 life. If you do, return Corpses of the Lost to its owner's hand. (You descended if a permanent card was put into your graveyard from anywhere.) | Izzy

Poetic Ingenuity | Enchantment | | Whenever one or more Dinosaurs you control attack, create that many Treasure tokens. Whenever you cast an artifact spell, create a 3/1 red Dinosaur creature token. This ability triggers only once each turn. | Kieran Yanner

Growing Rites of Itlimoc // Itlimoc, Cradle of the Sun | Legendary Enchantment // Legendary Land | | When Growing Rites of Itlimoc enters, look at the top four cards of your library. You may reveal a creature card from among them and put it into your hand. Put the rest on the bottom of your library in any order. At the beginning of your end step, if you control four or more creatures, transform Growing Rites of Itlimoc. // (Transforms from Growing Rites of Itlimoc.) {T}: Add {G}. {T}: Add {G} for each creature you control. | Josu Hernaiz
