What's the most beautiful card to you? 

I love Darnassus Aspirant, Holy Champion and Ancient of War

As a mill druid aficionado and regardless, that would be Grove Tender. 

Obviously Hobgoblin

I like malorne and priestess of elune for the moon/planets that rotate in the background.

Harvest golem is also a really nice one.

I really like Truesilver Champion, but it's not nearly as cool looking in the non-golden version.

Wild Growth

The best art has to be a Golden Alexstrasza.

Millhouse Manastorm for sure

Mysterious Challenger, Boneguard Lieutenant, and Powershot have been, my favorite from tgt.

i really like Brave Hunter

i have a feeling it's going to look amazing in golden.

Golden Innervate

Master of Ceremonies

I really have a thing for the Secretkeeper's art.  I also like Master of Ceremonies.  I'll leave it to the imagination to decide why :p

Unstable portal also looks cool.  A wizard casting a spell and a huge mountain appears... I mean, who can't love that?  Duplicate also has quite neat art; it is the only naxx/brm card I have crafted in golden so far.

Trade Prince Gallywix is pretty funny looking, too.  He reminds me of a cross between Jabba the Hutt and pretty much every male Disney villain ever.  (who I suppose is also now a Disney villain...)

Master of Disguise is also nice.  (see secretkeeper/master of ceremonies)

Power Overwhelming.  The guy on the art just looks like he won the lottery or something.

Twisting Nether.  So apocalyptic.  The black hole is just sucking everything in :p

Doomsayer.  He just looks like a boss, and his colour scheme is awesome.

Explosive sheep.  It's an exploding sheep.

99% of all golden cards, -especially- some of the dragons.  Golden alexstrasza and golden malygos look AWESOME.

The golden version that I like so much is Mirror Entity... The colors, the effect is really amazing!

You pervert.

:p

Twisting Nether,the art is beautiful and the play animation is the best in the game IMO.

Chillmaw ^^

Ragnaros the Firelord, Baron Geddon and Lord Jaraxxus off the top of my head.

 Orgrimmar Aspirant
