The four cards on offering are: Prosper, Tome-Bound (a Legendary Creature), Xorn (an Elemental Creature), Wild-Magic Sorcerer (an Orc-Shaman Creature) and Grim Hireling (a Tiefling Rogue Creature)
The morph mechanic then allowed players to pay a certain cost, almost always mana, to turn the card face up and turn into whatever creature was on the face-up side
The biggest difference is that Rayami wants those cards to die on the battlefield, so sacrifice outlets are important, whereas Indominus Rex wants those cards in your hand, which it can then easily refill with its own ability
