Echo Chamber copies any creature that attacks you, matching its power, toughness, and creature types for as long as it sticks around — which is the catch: it costs four mana to activate and doesn't untap naturally, so you get one copy per opponent's swing unless you're building around it. It's a niche political and defensive tool, not a generalist staple.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Echo Chamber is legal in Commander, Legacy, Vintage, and Oathbreaker, but its real home — really its only home — is Commander. In Legacy and Vintage, a four-mana artifact that requires an additional four-mana activation and doesn't untap on its own is far too slow against the formats' consistency and combo speed. In Commander, the multiplayer dynamic changes the calculus: three opponents swinging creates three potential copy triggers per round, and the political angle of matching an attacker's stats can deter combat or fuel token synergies. Even in Commander it's a role-player, not a staple, but that's the format where Echo Chamber at least earns its slot.

Price Context
Current price
$0.46 bulk tier
At $0.46, Echo Chamber is firmly bulk — a throwback rare that never found a wide audience and shows no signs of spiking. Pick it up cheaply if the build calls for it, but don't expect the price to move in either direction.
