Dracogenesis

Free-cast enchantments have a long red lineage that trades a heavy up-front investment for an engine that turns every future spell of a chosen kind into pure upside, and this one narrows the payoff to Dragons specifically. Eight mana buys no body and no immediate board impact by itself, just the standing permission that every Dragon spell you cast costs zero. That is the whole tension. Where similar cost-reduction pieces hedge by shaving a generic mana or capping the discount, this one goes all the way to free, and pays for it with a mana value steep enough that the enchantment usually resolves a full turn or two after you would like your first Dragon to. The Dragon-only clause is a deliberate leash on what would otherwise read as a general storm enabler; it only rewards a deck already committed to the tribe, where the density of castable Dragons is high enough that "free" compounds into a chain rather than a single blowout. Note the wording covers Dragon spells, not just creatures, so any Dragon-typed noncreature card rides along for free too. The card is less a value engine than a lever: dead the moment it lands, backbreaking the moment you untap with a hand full of the one card type it cares about.
