Can Stardust Dragon negate Hero Blast, and if it does, does Hero Blast still add the Warrior to hand?✓
Your opponent activates Hero Blast targeting a monster you control, and you control Stardust Dragon.
Stardust Dragon can negate Hero Blast if it is going to destroy a card you control. If the activation is negated, Hero Blast does not resolve, so the Warrior is not added to hand.
Can you activate Hero Blast if your opponent controls a face-down monster?!
Hero Blast is activated with a normal HERO in the Graveyard.
Yes. Hero Blast does not require the opponent's monster to be face-up.
