Ridgescale Tusker
The counter distribution scales with your board, which makes the trigger a referendum on tempo: cast it into an empty battlefield and you have a 5/5 for five whose ability does nothing, but cast it with three or four creatures already deployed and it functions as an anthem that arrives all at once and stays. The "each other creature" clause is the load-bearing restriction. It excludes the Tusker itself, so the card is always doing better work as a follow-up than as an opener, rewarding the player who has committed bodies first rather than holding it as a standalone threat. Because the counters are permanent rather than a turn-long pump, this is a midrange beater dressed as a go-wide payoff: the buffed board survives a single sweeper better than a temporary buff would, and the counters stick even if the Tusker itself is bounced. What sets it apart from a plain green stompy fattie or a token-flood anthem is that it belongs to neither camp cleanly; it sits in the gap between them, asking only that you sequence your creatures before your five-drop rather than around it.
