Bone Dragon

Exile seven other cards from your graveyard. That price is the entire strategic weight of this card, because seven is not an incidental toll but a deliberate floor: it demands a yard actively engineered to be fed, then treated as ammunition rather than a resource to hoard. A 5/4 flier for five mana is honest, unremarkable stuff on the battlefield; the second life is the whole draw, and it strip-mines the graveyard it depends on so that each return costs as much setup as the first. That self-consuming toll is what stops an evasive recurring threat from grinding an opponent into dust unopposed. The tapped clause is the other governor: it comes back without a body to swing, offering a window for an answer before it can attack, which is the concession that pays for a five-power flier crawling out of the yard at all. Structurally it belongs to the black tradition of threats that pawn graveyard mass for permanence, the lineage running through Nether Shadow and Bloodghast, but pitched higher and taxed harder. The evasive body is the reward; the seven-card exile is the invoice that comes due every time you cash it.
