Mad Dash doubles everything it promises (rules rev 12)

'Including NUMBER cards and other add-ons' now means it: a number
riding the cast fuels the dash — (base + number) × 2 — and numbers or
POWER RUN points played under it double as well. The 5BM4 five that
vanished into a borrowed 'burns 0 life for speed' line gets its own
madDash event and chronicle voice. Older games doubled only the base
and replay so, pinned at deckRev 11.
