Yesterday on If somebody steals my creature, …

Heh, cheers.

At first I was confused about whether player C would steal my friend or not, but it began to make more sense to me as I typed it out.

I guess I'm just mostly curious about the 'when' part of the text. I initially thought that each batch of wish cards would only be castable by your friends that helped pay for that respective batch. But actually another player becoming your friend seems like a more general thing that lasts the whole game and doesn't specifically suggest that restriction. So in the original example, if I were to activate the ability of another Nightmare Moon  ^Flip at a later point in the game (by paying in full, myself), player B would still potentially be able to cast the cards I find.

Are there any black-bordered examples of "Whenever a player activates this ability"? The closest things I'm coming up with are Ashling the Pilgrim or Burning-Tree Shaman.

I'm... not having a breakdown, just trying to understand something silver-bordered.

I (player A) own and control Nightmare Moon  ^Flip. Player B pays [6] to activate its ability. In response, player C casts Act of Aggression targeting my little pony, and the stack resolves.

I'm thinking the 'when they do' text means it's a triggered ability that's put onto the stack after paying the cost of the activated ability. So that triggered ability would still be on the stack at the time Nightmare Moon was stolen, and would resolve after player C steals the creature but before it transforms?

So player C steals my creature, it transforms and so player C gets the triggered ability from Princess Luna transforming, wish-tutors, but doesn't have any friends? And I do have a friend, but without benefits?

Does that all seem right?
