Forum:GOYO VS Gottoms' Emergency Call

Please help me WHEN Goyo destroys a my monster x-saber and my opponent activate the effect of Goyo to Special Summon that monster to your side of the field, I can turn Gottoms' Emergency Call on the chain effect of goyo? I have the correct timing? I was told that the effect of Goyo is activated during the Damage Step is CORRECT?

goyo guardian When this card destroys an opponent's monster by battle and sends it to the Graveyard, you can Special Summon that monster to your side of the field in face-up Defense Position.

Gottoms' Emergency Call Activate only if there is a face-up "X-Saber" monster(s) on the field. Select 2 "X-Saber" monsters in either player's Graveyard(s). Special Summon those monsters to your side of the field.

THANKS Davide
