Silly people on the main subreddit are complaining that the Dungeon Mechanic is parastic, which basically means it doesn't interact well with other mechanics which is bs. The Dungeon can trigger life gain, treasure and creature tokens, force sacrifices, etc..., all of which interact with cards from previous sets, from Goblin tribal, to Magda, to Vito, to Heliod, to Purphoros, to that Assembly Worker from MH2, that enchantment that grants a bonus squirrel token when creating other tokens, Divine Visitation turning tokens into 4/4 Angels, etc...,
And trigger a venture itself has plenty of interactions from flicker effects, to cards that cause enter the battlefield effects to go off twice, to Emberclever giving that blue rogue that ventures when dealing damage to a player double strike and trample.
