Forum:Gladiator beast war charriot Q

i have some question about the activation of this card 1 When the effect of gorz its activated by a direct attack, war charriot will negate the gorz when he hits the field and tries to special summon the token or will negate him when he is still on hand like the effect of liggth and darkness dragon? I have the same doubt with tragoedia 2 if multiples monsters effects activate at the same time, can I activate war charriot to negate the one I preffer?, example: i have a murmillo face up and mirror force and war charriot in the backrow, and my opponet has a card trooper and sangan in his side of teh field, he attacks i activate mirror force destroying both monsters and activating both effects NAZS
