therm plug is a lot better than onxyia. for example you could burn a field with wild pyromancer and get a huge value out of it. Onxyia plugs the field and is a target for MCT, BGH, and even a weak board clear will completely stripe all value of playing 9mana minion. both cards are very nitchy tho and not very good cards to start with. the real question would be why play anything other than doom, rag, and alex.
I played the weirdest druid deck today. With the help of the Emperor, he put out a Knife Juggler followed by Onyxia. This might be the only time Ony has ever been played where I couldn't think of a better drop instead. <_<
Asides from the fact he's a mech.
My legendary count excluding adventure legendaries, dupes and old murk eye: 40
$$$ spent on this game: 0

Personally, i wouldn't play either card in any sort of competitive deck.

There's no reason to play most 8-10 drops when Boom is better and costs only 7 mana. Even Rag is better than Therma.
