How does Relentless Punishment work with Power Cards that Repeat themselves (e.g., "The Land Thrashes in Furious Pain")?

How does Relentless Punishment work with Power Cards that Repeat themselves (e.g., "The Land Thrashes in Furious Pain")?

In order:
  • The initial use of the Power targets a land and resolves
  • This triggers both "Relentless Punishment" on that land and the Power's own Repeat instruction. Since the order is ambiguous, you choose which one happens first.
  • After the Power Repeats itself, "Relentless Punishment" triggers again on the second land targeted.
Because "Relentless Punishment" counts all prior uses of the Power, using that special rule a second time can get quite expensive (Power's Energy Cost + 1 Energy for the first use + 1 Energy per initial "Relentless Punishment" use + 1 Energy for the self-Repeat use)!
The Locus Aspect works similarly, but instead of the cost increasing each time, each Repeat counts against the number of Repeats that Spirit gets from "Strength of the Waking Island."
