My amazing friend  SunsetScorpion did the art for this, I made it into a card with my favorite card back and everything ^ ^

I wore this at Furry Down Under 2018 and so many people loved it and wanted their own Hearthstone card badge. I am surprised I hadn't seen any like this already O_O

It has 3 sizes because the small one is for clipping to me if I'm wearing another badge on my lanyard, the medium one is for normal lanyard wear, and I wear the big one while suiting.

Koth's battlecry effect applies Warlock's "Corruption" to all enemy characters, which includes the enemy hero. The only way to remove it is to play a hero replacing card.
The only difference is that Koth's corruption prevents any effected minions from having their form changed (hex, evolve, polymorph etc) Koth himself may be a druid, but he is actually stuck in his wolf form because of the corruption.
If this battlecry is triggered twice, it instantly kills all enemy characters.
