Dragon's Approach
Most cards enforce a four-copy ceiling; this one revokes it explicitly, granting a deck permission to run as many copies as it can jam in. That license is the actual mechanic. On its own the spell is a modestly overcosted burn effect, three damage to each opponent rather than aimed anywhere. The graveyard clause is what redeems it: exile this copy plus four buried ones to tutor a Dragon straight onto the battlefield for no mana. Every copy therefore plays three roles at once, chipping away at life totals, banking in the graveyard, and functioning as one-fifth of a free tutor. Both uses draw from the same pool of copies, so the number of Dragon's Approach in the deck is very close to the number that decides whether the deck functions at all. Other pile-payoff designs suspend the four-of rule for volume alone (Relentless Rats, Rat Colony, and Persistent Petitioners all reward hoarding identical cards), but Dragon's Approach pays the pile off in two unrelated currencies: enough resolved copies burn the table out, and enough copies milled or drawn into the graveyard cheat a haymaker onto the field early. What prints as a sorcery is really an invitation to break the deckbuilding rules, and the archetype it authorizes is the point, not the three damage.
