Boggart Mob

Champion remains one of the strangest "ETB tax" mechanics ever printed: it demands you exile a Goblin you already control to keep this creature, then promises to return that card when this leaves. The exiled Goblin re-enters as a fresh permanent when the loop closes, retriggering everything that cares about a Goblin entering, while this creature's death or bounce snaps the original back into play. That bookkeeping buys the body, and the body is meant to make the loop pay: every Goblin that connects in combat offers another 1/1 Goblin Rogue token, which becomes another attacker, which becomes another token. The 5/5 frame matters because it can push damage through without help; the rest of the team turns that pressure into a widening board rather than a single lethal swing. What gives the card its character is the way the two abilities pull against each other. Champion shrinks your team by one creature the instant it arrives; the combat trigger rebuilds it, but only if you can land damage. There is no static buff here, no lord effect: just a payoff that converts unblocked tribal damage into bodies, so a turn where nothing connects leaves you down a creature with nothing to show. It belongs to the school of tribal payoff where the creature is less a finisher than a node in a recursion-and-tokens chain, rewarding a board already committed to Goblins instead of a deck splashing for a closer.
