Charging Hooligan

The math here is the wide-board tax paid off in a single body: each attacking creature adds +1/+0, itself counted, so a four-mana 3/3 that swings alone connects as a 4/3, while one that crashes in alongside five friends arrives as a 9/3. That scaling structure makes it a payoff for go-wide decks rather than a card you cast to trade one-on-one, since the bonus is only worth building around when the rest of the board is already committed to the attack. The Rat clause is the tell about its intended home. Trample appears only when a Rat is attacking, tethering the card to a specific tribal engine and converting what would otherwise be a fat, blockable body into one that shoves overflow damage past a wall of chump blockers. It is a conditional keyword grant used as a soft build-around: it rewards a board you were already assembling rather than handing the ability out for free, and it costs nothing in decks that were never going to field a Rat in the red zone. Note that the pump stays entirely in power, so the extra size never helps this creature survive a block, only close a race. On an empty board it is a marginal beater; in a swarm it becomes the finisher that ends the race the small creatures opened, with trample ensuring the last points cannot be gummed up by tokens.
