I'm thinking Waxadred.

I'm much more stylish than my kin, Waxadred is a Dragon made from candles so I guess you could call him stylish.

I wield that which sears the skin, Waxadred in his card art seems to have hot wax which might burn your skin if you touch it.

The crowd cheers when I fight,                 I'm thinking it's either the intro music when a Legendary is played, or could be the cheering when you attack with it since it has 7 attack.

My deck never took flight,                  Shuffle Rogue never really became a thing and is overshadowed by Deathrattle Rogue even thought they received some neat support like Stowaway.
