Does Eclipse Herald get +1 might and ready from stuns that occurred earlier in the turn before it was played, or only from stuns after it enters play?

Ruling: Eclipse Herald only triggers from stuns that occur after it is on the board. It does not retroactively gain +1 might or ready from stuns that happened earlier in the turn.

Nuances:

• Some effects like "When you've played your 2nd card this turn" do track actions from the entire turn, but Eclipse Herald has a specific trigger that only becomes active once the card is in play
• Eclipse Herald gains +1 might from its effect, which is technically not a "buff"
