Vivien's Invocation + Forerunner of the Heralds [Investigating]

If i cast Vivien’s Invocation and fetch Forerunner of the Heralds (4/3) which then asks me to fetch a merfolk.
The Vivien’s Invocation will deal damage equal to the power of the merfolk fetched by the Forerunner, not the Forerunner which was fetched with the Invocation.

Interesting. Thank you for the report. I’ll pass this along to the team for review.
