Hydra Broodmaster (PRM 53850 foil) is a Rare creature Hydra from the Magic Online Promos set. It has an activated Monstrosity X ability that puts X +1/+1 counters on it for {X}{X}{G} and, when it becomes monstrous, creates X X/X green Hydra tokens. Its high base stats and token generation make it a late-game threat that scales with the chosen X value.
