Echoing Assault

Enchantment

Creature tokens you control have menace.
Whenever you attack a player, choose target nontoken creature that's attacking that player. Create a token that's a copy of that creature, except it's 1/1. The token enters tapped and attacking that player. Sacrifice it at the beginning of the next end step.

Echoing Assault card art
Echoing Assault doubles every triggered attack ability your creatures have — the payoff lands immediately on any creature that triggers on attack and scales hard with multiple attackers. The cost is real: you need a deck built around attack triggers to justify the slot, and Zinnia, Valley's Voice is the clearest proof of concept.

Commanders with the highest synergy

01
Zinnia, Valley's Voice

Zinnia, Valley's Voice

42.6% of decks · synergy 0.39

Zinnia, Valley's Voice creates a copy of each creature that attacks, meaning Echoing Assault effectively doubles that doubling — every attacker triggers twice, every copy triggers twice, and the board-state compounds faster than opponents can answer it.

02
The Master, Multiplied

The Master, Multiplied

35.5% of decks · synergy 0.33

The Master, Multiplied wins by flooding the board with token copies of itself, so Echoing Assault turning each of those attackers into double-trigger engines accelerates the damage and ability output that the deck is already trying to maximize.

03
Deadpool, Trading Card

Deadpool, Trading Card

34.0% of decks · synergy 0.32

Deadpool, Trading Card generates value from dealing damage and from his own attack triggers, so Echoing Assault doubling those triggers means more draws, more pings, and more recursive nonsense per combat step.

04
Zurgo, Thunder's Decree

Zurgo, Thunder's Decree

26.9% of decks · synergy 0.26

Zurgo, Thunder's Decree cares about Warriors attacking and punishes opponents for blocking, making Echoing Assault a clean way to double the triggers that fuel his damage-dealing and lord effects each turn.

05
Mabel, Heir to Cragflame

Mabel, Heir to Cragflame

24.0% of decks · synergy 0.22

Mabel, Heir to Cragflame grows and generates equipment-adjacent value whenever she or her team attacks, so Echoing Assault stacking a second trigger per attacker means faster counters and more equipment tokens with no additional mana investment.

Echoing Assault is a Commander card — full stop. It's legal in Legacy and Vintage but has no competitive presence there because the attack-trigger density required to make it worth a slot simply doesn't exist in those formats. In Commander, where attack-trigger commanders are a defined archetype and combat happens every turn, Echoing Assault earns its slot in any deck built around that axis. Oathbreaker is the only other format where it sees any real consideration, and again only in shells deliberately stacking attack triggers.

Price Context

Current price

$0.34 bulk tier

At $0.34, Echoing Assault is deep bulk — you're paying pennies for a card with a narrow but genuine home. Bulk rares that spike tend to do so because a new commander pushes the archetype; as long as Wizards keeps printing attack-trigger commanders, the floor here is stable.
