Riot Ringleader

The attack trigger here is the cheap version of the Human anthem, and the limitation is built into the verb. The boost only fires on attacks and only adds power, not toughness, so this is a card that pays out exactly when the rest of the team is already pointed at the opponent and gives nothing back on defense. That makes it a curve-topper for a wide tribal board rather than a static lord: it does not raise toughness to survive a sweeper or save a creature in combat math, it just turns a flat board into lethal one turn sooner. The body itself is part of the count it pumps, so a swing with a few other Humans alongside scales fast, and the effect resets each turn rather than sticking. In the long lineage of tribal payoffs, this sits firmly on the aggressive end, closer to a one-shot battle cry than to the permanent stat-line lords that hold a board together. The design tradeoff is honest: a smaller, attack-only buff in exchange for the cheapest slot a Human anthem could reasonably occupy, aimed squarely at decks that want to empty their hand and finish before the trade-down catches up.
