I was in the battle subway with a parted (not real life partener) she had a chandelure with heat wave and she dominated!! What do you have to breed to get a chandelure with heat wave?
Here are the steps:
1. Get a Male Slugma or Magcargo in Gen IV and teach it Heat Wave via Move Tutor.
2 Blue Shards
In HeartGold/ Soulsilver:
The tutor can be found at the Frontier Access.
Poke Transfer it over to your Gen V game.
Get a female Litwick, Lampent, or Chandelure and breed it with the Slugma or Magcargo that knows Heat Wave.
The Litwick baby will now know Heat Wave

If you looked this up yourself ( http://pokemondb.net/pokedex/chandelure ), you would've found out you have to breed it specially to get Heat Wave.
