- Best for
- Best for boards that already fire the keywords on this relic built around Rush.
- Skip when
- Skip when you rarely trigger Rush, or a cheaper enabler would stabilize the board first.

- Legendary late luxury. Prefer it when the board already leans this direction. Stack Rush support around it. Read the trigger line before you lock it — condition frequency matters more than the number.
