Overview
Benevolent Hydra is a scalable green creature that anchors +1/+1 counter strategies. It enters the battlefield with X counters based on how much mana you invest, passively improves all counter placement on other creatures you control by adding one extra counter, and can tap and remove a counter from itself to put a counter on another creature. That trio—front‑loaded stats, a teamwide enhancement, and targeted redistribution—makes it both threat and engine in decks that care about counters.
How it plays
As an early play for X=1–2, the Hydra establishes a body and immediately improves future counter growth from effects like Rishkar, Luminarch Aspirant, or Adapt/Evolve creatures. As a mid/late topdeck, sinking 4–6 mana produces a sizable attacker that also supercharges your board’s development. The static enhancement applies only to other creatures, so the Hydra doesn’t snowball itself, but the tap ability lets you move its counters outward at instant speed in response to removal or to push combat math. Because it requires tapping, you’ll usually deploy it before combat and leverage the activation on later turns or after it loses summoning sickness. Replacement effects stack—pairing with cards that add extra counters turns each placement into a burst of growth.
Decks & synergies
- +1/+1 counters shells: Works with Hardened Scales, Conclave Mentor, and Winding Constrictor; multiple “add one extra” effects stack for explosive scaling. (Oracle text confirms it boosts counters on other creatures you control and has a tap ability to move counters.)
- Token/go‑wide: Turning a stream of small counters into bigger ones across your army makes anthem effects and overrun finishes lethal much sooner.
- Modular/Energy/Adapt/Evolve: Any mechanic that places counters repeatedly benefits; moving a counter can also “turn on” abilities that check for counters.
- Counter recursion: Combines cleanly with The Ozolith, proliferate effects, and creatures that ETB with counters you want to magnify.
Sequencing & tips
Cast Benevolent Hydra before your primary counter engines to maximize value over time. Use the tap ability to save important creatures from damage (move a counter to grow them out of burn range) or to create surprise lethal by shifting counters onto an evasive or trampling attacker. Remember that the static boost doesn’t help itself; if you need the Hydra to grow, plan to feed it counters from other sources and then distribute them later.
Formats
At its best in Commander and casual constructed where counter synergies are dense. It’s legal across eternal formats but primarily shines at tables that can stack Hardened‑Scales‑style effects and enjoy intricate combat math.
