The Cruel Hand of Timmy
ATT 2, Pay 3

When your hero deals combat damage with The Cruel
Hand of Timmy to a hero, that hero's controller destroys
one of his resources.


So When I strike with it and my opponent uses armor to prevent
the damage, is combat damage dealt then? so my opponent has to
destroy a resource?

I say yes. Combat damage is when you stike.
My opponent said no, you had to do damage to my hero, not in his armor.

Your opponent is correct, combat damage is only dealt when the hero takes damage, the armor prevents the taking of damage.

Damage that is prevented is not dealt. So the short of it no. Your opponent is correct. Now if you are a paladin or an "armor" wearing class there are ways to stop the prevention. ie Lionheart Helm or Spread the Word. If you are Horde you can run Hur Shieldsmasher. Just some ideas to help you continue to wreck their face.

Have a nice day

Thank you guys, thank you

you are not dealing damage when you strike with a weapon. you are adding that weapon's attack value to your hero's attack for this combat. you don't deal damage until combat resolution, and at the damage prevention point if you use armor to prevent all damage that is scheduled, no damage is dealt and cruel hand of timmy does nothing.
