Avenging Huntbonder

Double strike is one of white's rarest handouts, and this creature turns a one-off keyword into a repeatable, permanent transfer. The body is unremarkable: a 3/3 that hits for six on the swing. The value is what it grants downstream. Each attack pins a double strike counter on another attacking creature, and because it deposits a counter rather than a temporary grant, the buff never wears off. A single trigger converts a fragile evasive threat into a lethal one, and successive attacks compound the effect across a board. That permanence is the pivot: most damage-doubling in white arrives as a combat trick or a one-turn enchantment, expiring the moment the step ends, so building a wide, sticky attack force never carried much upside. Here the doubling accumulates on whatever survives, which quietly rewards the exact go-wide boards white anthem effects assemble. The natural payoffs are creatures whose combat-damage math doubles alongside their swings: lifelink gains, trample spillover, or any combat-damage trigger that now fires twice per creature per attack. The design tension is that the counter only lands on something already attacking, so the card demands a real assault to matter rather than sitting back as a value piece. Commit to the swing and it snowballs; hold it back and it is a five-mana 3/3 with a keyword.
