Caller of the Hunt

The asterisk-power gamble made literal: you commit to a creature type as an additional cost before the spell ever resolves, and from then on the body reads the board continuously, sizing itself off every creature of that type in play. This is a characteristic-defining ability, not a snapshot, so the power and toughness float up and down as the chosen type's count changes; remove enough of those creatures and the body shrinks on the spot. The additional-cost framing is where the real friction lives. Choosing the type happens during casting rather than on resolution, so an opponent who sees it coming can respond to the cast and thin the relevant creatures before it lands, deflating the thing before it ever enters. It counts every matching creature, yours and theirs alike, which means a mirror full of the same type can balloon it to absurd sizes, and an empty board can shrink it to little more than the creature itself. That dependence on a populated battlefield is the whole identity: three mana that does nothing in a vacuum and turns into a finisher that scales with the metagame in front of it rather than with anything in your deck. It belongs to the early lineage of creatures whose stats read the room instead of being printed flat, an ancestor of the many later bodies that measure themselves against a running count of something on the battlefield.
