Breaching Dragonstorm

Impulse-draw enchantments usually fire once on entry and then sit there as inert cardboard, having spent their whole value in a single trigger. This one solves that dead-permanent problem by wiring the reset into its own tribe: every Dragon that enters under your control bounces the enchantment back to your hand, ready to be recast for another dig. That bounce is the entire engine, and it runs one direction only. The dig is strictly an enter-the-battlefield effect, so a resolved enchantment on the battlefield does nothing but wait for a Dragon to send it home; there is no reason to leave it there once you can recast it. Each new flyer converts a one-shot Free-Spell dig into a repeatable one, exiling down to a nonland card and either casting it outright (when its mana value is eight or less) or slipping it into hand otherwise. The eight-mana ceiling on the free cast is what keeps the effect from cheating out anything you please: it rewards a curve stacked with playable midrange spells rather than a single fatty parked on top of the library, since a whiff into something too expensive just becomes a card in hand. The skill lives in Dragon density, not in holding the enchantment back. The more consistently the deck lands Dragons, the more times the cycle fires, and a build that cannot reliably do so is left with a five-mana cantrip that never comes home.
