Standard?

It's an automatic whenever

You can't respond to a heroic trigger

[Ieatfood7]

You can respond to anything when you have priority, and unless its a mana ability, all activated and triggered abilities use the stack. How do you think {stifle} works if it can't respond to triggered abilities? 

I'll find the rule for you. It may take a minute.

Ok
So I lose hoplite
No damage goes thru (blocker declared)

[Ieatfood7]

Correct. No damage to you. Your turn.

I didn't find the numbered rule in the comprehensive rules, but before PTQ, you may want to google: mtg salvation magic 101 triggered abilities

It explains it well.
