Does anyone still use this?

Using it now in my Reno deck. At first I added it just for lulz and because I noticed myself picking Corruption quite often from Dark Peddler options, but card turned out to better than I thought. It is great answer to OP 1-drops like Mana Wyrn or Trogg, which are actually very hard to counter otherwise with Dark Bomb gone now in Standard. Apart from earlygame its not so great, but never worthless as it provides options in fighting for board control. 

I just want to point out, that this pairs very nicely with the freezing spare part and Frost Elemental for a free kill on almost anything.

This card can be totally OP. I just spend coin + 2x Innervate to play a 6-mana minion on turn 1. That's 4 cards in total plus an entire turn spent. The warlock just destroyed it for the measily cost of 1 mana. It's retarded.

do you like golden animation?

Back when I first started playing I used to use this card all the time with Frost Elemental. Still not great, but better than nothing when I didn't have Siphon Soul

Dangerous to use on strong minions, which are exactly the ones you want to use hard removal on, because they get to whack on you or do their thing for a turn before they die.  Possibly freezing them or putting taunts in their way would help the whacking part, or just use Siphon Soul, though it costs 6 mana crystals.
