Another deck from Nick, haven't tried it, but plan to.
He says he's planning on making it better, so I'll update it when he does
Here's my latest version of the hybrid Uber/Blitz Kerebrus. This deck is all about the big K, but it's a lot more focused on making him nigh indestructable than on boosting his ability to hit. His ATK goes up slowly, which is fine as he tends to have enough to deal with whatever he's facing at the time. Try this one out, especially if you haven't had luck with a Kerebrus deck before.
BTW, this deck contains 5 rares aside from K, and only has Yscar because there aren't any common level 3 mercs yet. The Sakarian Giant will take his place quite nicely.
---Move Kerebrus up as quickly as possible, most likely he'll be swinging on the second turn. The play is fairly obvious from there, just make sure to pile stuff on Kerebrus to keep him alive.
