Terror of the Peaks turns other creatures entering under your control into damage. Each arrival triggers damage equal to that creature’s power, aimed at any target. That gives Dragon and creature-value decks a way to remove blockers, pressure life totals, or finish a game without relying entirely on combat damage.
Large creatures provide the most obvious payoff, but repeated smaller entries can add up as well. Panharmonicon can produce another trigger when a creature entering causes Terror’s ability to trigger. Blink effects can let a creature enter again, combining its own entry ability with another burst of damage from the Dragon.
Helm of the Host offers a way to create additional copies of Terror. Each established Terror can trigger for later creatures, increasing the damage generated by the deck’s normal development. Urza’s Incubator can also help a Dragon-heavy list cast its threats more efficiently, leaving more mana available to protect Terror or deploy another creature during the same turn.
Terror does not trigger from its own entry, and the damage is based on the entering creature’s power rather than its mana value. A group of 0/1 Plant tokens therefore needs a different plan than simply assuming their entry deals significant damage. Opponents’ spells targeting Terror require an additional three life to cast, but that is a cost rather than immunity to removal and does not apply to abilities. Establish it when you can follow with meaningful creature entries and gain value before opponents remove the engine.
