First123 is right. The design actually fits warlock because both in standard and wild they have access to disruption tools - both hand and deck.
Tick being played as corrupted is in 90% 8 mana 8/8 that is horrible in these days with very strong battlecry. I guess it would still be played even as 5/5 because stats doesnt matter that much.
I was wondering if it would be better or worse if it would target yours or your opponents hand instead.
That way it could be used in discard warlock and it wouldnt count towards fatigue. Not to mention sometimes your opponent would have less than 5 cards on the hand (fast decks) thus it wouldnt play its effect in full.
Though I am still not sure if its better or worse. It would screw combo and control in pretty funny way though it does that already.
On the other hand it might lead to your opponent being unable to play anything thus gaining a huge advantage. I have won a lot of matches where I had discarded 10 cards just because I was preparing for that situation. If it would annihilate my hand twice, I guess it would be just gg.
