Savageborn HydraHow it works & interactions with other cards

Variable Strength and Growth

Savageborn Hydra enters the battlefield with a number of +1/+1 counters equal to the mana spent on its X cost. However, its potential doesn't stop there. By spending one mana and one hybrid Red/Green mana, you can add additional +1/+1 counters to it. Note that this activated ability can only be used during your main phase when the stack is empty, as it follows sorcery speed restrictions.

Double Strike Mechanics

Because this creature has double strike, it deals both first-strike and regular combat damage. Any +1/+1 counters you place on it effectively count twice during the combat phase. If it has three counters, it deals 3 damage during the first-strike step and another 3 during the normal combat damage step, totaling 6 damage.

Common Timing Mistakes

The most common error is attempting to pump the Hydra during combat or in response to a removal spell. Its ability to gain counters is limited to 'sorcery speed.' This means you must commit your mana to grow the Hydra before moving to the combat phase or passing the turn.

When to Deploy

This card is an excellent mana sink. Early in the game, it can be a modest threat, but in the late game, it becomes a massive finisher. Since it lacks natural protection like hexproof, it is often best played when you have enough mana to make it a significant threat immediately or when your opponent is tapped out.

Interaction examples

Accelerating the Hydra

Llanowar Elves

On turn one, you play Llanowar Elves. On turn two, you play a land and tap both lands and the Elf to cast Savageborn Hydra where X is 1. The Hydra enters with one +1/+1 counter. Because of double strike, this 1/1 creature will deal a total of 2 damage if unblocked.

Fixing Mana for Growth

Birds of Paradise

If you have Savageborn Hydra on the battlefield and a Birds of Paradise, you can tap the Birds for Red or Green mana to help pay for the Hydra's activated ability. During your main phase, you spend two mana (one generic and one from Birds of Paradise) to put a permanent +1/+1 counter on the Hydra, increasing its damage output for all future combats.
