Welcome to progresses from turning opponents noncreature artifacts into Wall artifacts through creating 3/3 Dinosaur tokens with trample and haste, to finally destroying all walls and transforming the saga card into the legendary land card Jurassic Park Jurassic Park (the card) grants each Dinosaur card the Escape keyword - allowing them to be cast from the graveyard for their mana cost and the specific number of cards
Each level will offer a new ability or an instant return, such as grabbing a card from a graveyard
Note that if it was forked, you cannot win with it, as that won't count as "casting," but something that casts it for free from a non-hand source will count the first time, so something like Golos, Tireless Pilgrim can count as the first time you cast it, and net you seven life and stack it seven down
Witness Protection and the later in Lost Caverns of Ixalan released Eaten by Piranhas basically do the same things as Imprisoned in the Moon, except that they can only target creatures
These are exciting times for players of deNA's hit mobile game, as in addition to more promo cards coming to the game, the first mini-set has been released
A quick read, but an effective one
