Just played Arena and had Proud Defender as the only minion on the board. So it had 4 attack.

Then I played Mossy Horror to kill the 2-attack minions of my opponent by assuming that Proud Defender would survive, as "Battlecry" always triggers BEFORE the minion is actual on the board. But Mossy destroyed Proud Defender. 4 attack was reduced back to 2 during the battlycry.

This is a wrong interaction, right? At least the text of Proud Defender is extremely vague, "While you have" can mean anything! But it clearly doesn't mean "while you have on the board". Must be something between "in your hand" and "on the board". ^____^

Hey at least, now you know !

That's intended. You played a minion reverting proud to 2 then the battlecry went off, fits the stack.

Battlecries occur after the minion enters play, and after 'whenever you play' triggered effects such as those of Illidan Stormrage and Hobgoblin.

 Yeah, but apart from the fact that "whenever you play" is not in the text, "while you have" seems to behave the same and triggers before battlecries.

 As Majin said - at least, now I know.
