-----------------------------------------------------------------------------------------------
Description

"Hydra Dominion" is a Legacy mechanic-based midrange deck that embodies the pure power of green mana devotion. By combining Elven mana acceleration and the natural exponential growth of Hydras, this deck transforms small beginnings into overwhelming dominance. Each turn magnifies your presence, as every spell feeds the next, leading to explosive turns where your battlefield becomes an unstoppable force.

Through mana engines such as Priest of Titania, Rofellos, and Nykthos, Shrine to Nyx, “Hydra Dominion” creates absurd amounts of mana to cast massive Hydras like Kalonian Hydra, Primordial Hydra, and Polukranos, World Eater. These creatures snowball out of control, doubling in size every turn with the help of Hardened Scales and Vorinclex, Monstrous Raider. Card advantage from The Great Henge and Return of the Wildspeaker ensures the deck never runs out of threats, while protection spells like Asceticism, Heroic Intervention, and Vines of Vastwood keep your titans safe from harm.

This deck thrives in both multiplayer and 1v1 Legacy games, excelling against midrange and creature-based decks. Its balance of speed, resilience, and inevitability makes it one of the most powerful expressions of green’s natural supremacy.

How to Play

Early Game:
Begin by establishing your mana base with Llanowar Elves, Elvish Mystic, and Priest of Titania. These early creatures fuel your devotion and allow you to reach four or five mana by turn three. Use this tempo advantage to deploy medium-sized threats like Managorger Hydra or Llanowar Tribe. Keep a protection spell ready if your board is threatened by early removal.

Mid-Game:
Use Nykthos, Shrine to Nyx or Rofellos, Llanowar Emissary to unlock huge bursts of mana. Cast your key Hydras — Kalonian Hydra and Primordial Hydra — which grow exponentially with each attack or counter placement. Augment your board with Hardened Scales or Vorinclex to double all future growth. Draw cards through The Great Henge or Return of the Wildspeaker to maintain pressure.

Late Game:
With your battlefield established, finish the game using Finale of Devastation for X ≥ 10 to grant all your creatures +X/+X, trample, and haste for an instant victory. Alternatively, use Natural Order to fetch Craterhoof Behemoth and deliver a one-turn kill. Keep Heroic Intervention or Asceticism active to protect your field during the final push. Once the forest awakens, victory is inevitable.

Ideal Opening Hand:
A strong starting hand should contain:
Two lands (preferably one Forest and one Nykthos)
One early ramp creature (Llanowar Elves, Elvish Mystic, or Priest of Titania)
One early threat (Managorger Hydra or Hardened Scales)
One piece of protection or draw (Vines of Vastwood, Return of the Wildspeaker)

Mulligan any hand lacking early ramp or sufficient mana sources.

How the Mechanic Works

Establish Mana Density:
Play your Elves early to generate multiple green sources by turn two. Priest of Titania and Rofellos quickly multiply your available mana, while Nykthos scales your devotion exponentially.

Amplify Growth:
Hydras like Kalonian and Primordial Hydra double their counters every turn, and with Hardened Scales or Vorinclex, those counters grow out of control. Each new Hydra magnifies the total mana output through devotion, fueling even larger plays.

Deliver the Finishing Blow:
Once your mana reaches critical mass, use Finale of Devastation or Natural Order to fetch Craterhoof Behemoth for an overwhelming alpha strike. Every creature becomes lethal under its buff, ensuring a swift and decisive victory.

This mechanic-driven growth pattern ensures continuous scaling, giving the deck both momentum and inevitability once established.

Play Like a Pro – 5 Tips for Mastering the Deck

Ramp is everything — missing your early accelerators delays your entire plan. Mulligan for Elves and mana density.

Never cast your biggest Hydra unprotected — always have Vines of Vastwood or Heroic Intervention ready.

Use The Great Henge and Return of the Wildspeaker not just for draw, but as a mana and pump outlet.

Time your Finale of Devastation — X=10 is the sweet spot for guaranteed lethal when your board is ready.

Prioritize Priest of Titania and Rofellos — protect them at all costs; they are your real combo pieces.
