Hello my question is: if I target my Heroic with a enchantment or instant and my opponent uses a cancel or is able to kill my heroic using a instant in response of me casting my card, does the heroic ability still triggers? or does it go on the stack?
Yes, the ability still triggers and goes on the stack.
Hmm .. So just to make sure I understand if the heroic ability was for example gets to scry 1 but my opponent was to magma jet it, do I still get to scry even though my heroic dies?
Yes,absolutely.
The Heroic trigger goes on the stack when you cast a spell targeting your dude. Killing the dude doesn't remove the trigger from the stack.
Ok thx or answering my question
