Rumbling Ruin

Counters decks usually cash out their board with trample, menace, or a mass pump: some way to convert accumulated +1/+1 counters into unblocked damage. This does the arithmetic differently. Rather than granting an evasion keyword, it reads the board's total counter count and turns that number into a blocking restriction on the opponent's smaller creatures, clearing a lane on the turn it lands. The design puts a payoff at the top of a counters curve while itself carrying no counters at all, which is the subtle wrinkle: it rewards a board you built elsewhere, then arrives as a 6/6 that most of the swarm can no longer stop. The effect is a one-shot for the turn it enters, so its ceiling scales with how wide and how loaded the rest of your creatures already are (a single fatty with a stack of counters is enough to shut down a row of chump blockers). It answers a real problem for go-wide counter strategies, where a defending army of tokens or utility creatures can absorb an alpha strike no matter how large the counter total gets. Here that same total becomes the weapon: the more you invested in growing your team, the more of the opposing wall folds. It is a top-end finisher built for a specific engine rather than a generic beater, and it only pays off when the counters were already there to count.
