Is Storm Emeralda the Same as Pokémon Delta Reign?

If you follow Pokémon TCG releases, you have likely seen two names appearing together: Storm Emeralda and Delta Reign. Both expansions feature Mega Rayquaza ex and headline the current Mega Evolution era. Consequently, collectors are asking: is storm emeralda the same as pokemon delta reign?

The short answer is almost, but not exactly. Japanese set Storm Emeralda serves as the primary foundation for the international Mega Evolution—Delta Reign set. However, key differences exist in total card count, secret rares, and promo inclusions.
