I have three card clarifications that came up while playing games last night.
Treasure card "Proton Gem":
You may add this card to your spell face up. It counts as a Wild Magic card but is not discarded.
Interpretation 1: Spells are crafted before a round starts. The player places the treasure in place of either a source, quality or delivery card. When the player's spell is revealed the treasure is placed aside and the wild card action takes place.
Rebuttal: The treasure says the player can add it to the spell, but does not specify when.
Interpretation 2: A player composes its spell then when revealed the player adds the treasure to its spell and goes through the wild card action.
Rebuttal: Spells are composed before a round so the treasure can't be added whenever the player wants.
Delivery card "Nuke-U-Lur Meltdown":
3 damage, and 1 damage to each player adjacent to that foe.
Interpretation 1: The caster is considered a player. If the caster is also adjacent to the target for the caster will take 1 splash damage. Interpretation 2: The intent of the card would not be to have it damage the caster even if the caster is adjacent to the target.
Source card "Professor Presto's"
If you played a Wild Magic card as part of your spell, gain a treasure.
Interpretation 1: The action of drawing a treasure triggers once even if the player composes its spell with more than one wild magic card.
Interpretation 2: The action of drawing a treasure triggers once for each wild magic card in the player's spell.
