When playing Stormbringer after Darius, does Stormbringer use Darius's base Might of 5 or his resolved Might of 7?

Ruling: Stormbringer uses Darius's base Might of 5. A card is not considered resolved/played until its text is fully performed and it is in the trash.

Sequence:

• Darius is played (Might 5, with text that would make him Might 7 when resolved)
• Stormbringer is played while Darius is still resolving
• Stormbringer checks Darius's current Might, which is still 5
• Stormbringer resolves using Might 5
