Engine relic note
Engine relics should be graded by how quickly they affect real fights. Echo Chamber-style relics can be excellent when the deck already has draw, cheap actions, or repeatable payoffs, but they are weaker when the deck is still missing damage and block fundamentals.

- Raise the relic when it improves both good hands and bad hands.
- Lower it when the deck needs basic survival more than ceiling.
- Link it to build pages only when the payoff is repeatable.
Support check
Before treating Echo Chamber as a premium relic, confirm that the deck has enough card flow and relevant actions. If the relic only shines after several more rewards, mark the recommendation as conditional.
