Thundering Spineback

Two engines stacked in one body: a static anthem for the tribe and a repeatable token factory that feeds it. The lord effect rewards a board already wide with Dinosaurs, while the activated ability builds that board from scratch, each 3/3 trample token arriving already buffed to 4/4 the moment it joins its kin. That self-referential loop is the design conceit. A token maker that pumps the tokens it makes turns mana into an escalating threat curve rather than a flat one, and trample on those bodies means the anthem converts directly into damage that gets through instead of getting chump-blocked away. The cost structure is what keeps it from running away: seven mana to deploy and another six to crank out each token mark this as a top-of-the-curve payoff that demands a board state already worth investing in, not a value piece you drop and forget. Green's tribal payoffs have usually split the jobs (a lord here, a token generator there); folding both into a single card that scales with itself is the wrinkle at work here. Flood the board, then watch flooding the board turn lethal.
