Me again (erm unless I got it wrong).

Quote from a mage on beating a warlock:

"Step 1: poly pet
Step 2: counter spell
Step 3: fireblast
Step 4: fireball
Step 5: frost nova
Step 6: fireball
Step 7: fire blast,

needless to say easy win vs locks a lock without a pet is useless as a sack of rotting potatos"

Q. Will this work?  If not at what step would it fail and why?

P.S. Ignore this question if my answer was wrong. :P
