No, you don't, for the same reason: If a card moves from a hidden zone into a visible one, again we check for triggered abilities while the card is visible. Gaea's Blessing can only trigger while it's in the graveyard - but it doesn't have the ability there. Guerrilla Tactics also gets shut down this way.
