Yugioh Card Trooper rulings?

I know card trooper's effect "Once per turn, you can send up to 3 cards from the top of your Deck to the Graveyard. This card gains 500 ATK for each card sent to the Graveyard, until the End Phase. When this card you control is destroyed and sent to the Graveyard, draw 1 card." but it does not say weather it gain its 500atk bonus only by his own effect. So if i were to use "morphing jar", "Ryko, Lightsworn Hunter", or "Hand Destruction" does "Card Trooper" gain 500atk for each card i send to the graveyard by there effects?
