A type label is not a borrowed video-game formula
The announcement identifies Psychic/Fighting Mega Mewtwo X ex and Water/Darkness Mega Greninja ex as examples of dual-type cards. This establishes the cards’ two labels, not permission to apply the video-game damage chart, same-type bonus or ability rules. Use Pocket’s actual rules and card wording for battle decisions; this reference does not reproduce those text blocks.
Why launch dates can appear one day apart
The English announcement includes a precise Pacific opening time. Retaining October 28 at 6 p.m. PDT avoids silently converting a regional October 29 date into a different event. When comparing release notes, first compare zones and timestamps, then decide whether the underlying announcement actually disagrees.
Rental access is temporary evidence, not permanent ownership
The announcement describes six Dual Fusion rental decks through December 15, 2026 at 5:59 p.m. PST, with replacement when the next booster arrives. Treat that as an announcement snapshot: check the current app before relying on availability. Trying a rental strategy and owning its component cards are different states.
Do not derive the set code from a ranked season
The source separately names Ranked Match Season C1. No confirmed expansion-code field is filled from that season name. Card counts, pack-specific checklists and exact legality remain unverified on this page. Keeping those fields unknown prevents a plausible identifier from becoming a false database key.
