Forum:Debris + etc

i waz dueling my friend and he summon Debris Dragon which allowed him to special summon Card Trooper frm da graveyard, he sed he cant activate the effect of raisin the atk strength bt he can pay the cost. can he? also he says that whn it goes bac to the grave he gets to draw a card? also he says if he brings bac Dandylion in this way, that whn it goes bac to the grave he gets the tokens. does he? also he sed if he brings bac Lonefire Blossom that he can tribute it because thats a cost, bt that the effect of special summoning 1 plant monster frm the deck also works 2??
