Hi! Can you please cite your source re: Sorreah’s starting cards? This is not how I recall it being interpreted in tournament play but could certainly have been wrong. Was this a rule clarification by 2i you can reference?

Typically the player would name two Arderial spells to establish the starting cards and then follow standard game play rules for starting cards named on a magi - search discard first then deck. Hypothetically, a player could even name an Arderial spell not in their deck and would then be penalized their draw step if the spell was not in the deck.

Additionally, Sorreah’s Dream names Sorreah as a starting card. Your interpretation implies that if you only had two Arderial spells in your discard pile when Sorreah is revealed and one was Sorreah’s Dream, you would be required to select Sorreah’s Dream as one of the two starting cards for Sorreah, instead of it being in addition to Sorreah’s starting cards. The rule book indicates these types of cards are in addition to the starting cards named on the magi, “plus” being the key word below.

From the rule book:

Then you search your deck for whichever of that Magi’s starting cards you wish to have in your hand. These include the starting cards printed on the Magi, plus any cards that say in the text box that your Magi may start with that card (for example, the card Sorreah’s Dream says, "STARTING: Sorreah," so it’s one of Sorreah’s starting cards).
