edge and christian sustained damage

[dtbj]

hey... i need help for edge and christian using sustained damage... the older version of sustained damage says "can only be played if your opponent plays a manuever and you do not reverse it from your hand; does not end your opponents turn. .................." my friend used edge and christian whose superstar ability is: whenever a manuever or a reversal played makes you discard card(s), you may instead draw a same amount. when i used the card super punch on my turn, he used the card sustained damage and drew cards to reduce the damage as the text of sustained damage says discard any amount of card to reduce the damage by 2 for each card discarded... can he play the card sustained damage against me when i play a manuever?

he can play it but he wont be able to draw any cards from the sustained because its not forceing him to it's a option to discard the cards its on the omni fact under EandC abilty hope this helps
