This is an updated version of an older deck and it is still very fun.
The idea is simple - use kyrex coach driver to give deadly to as many units as possible that deal damage to units, the more the better. The best it get it on Black-Sky Harbinger, though Xo is a second best. If they don't kill KCD, then the deck starts rolling over them quick as almost every unit becomes a kill card or more. Use Crunch, Gorgon Fanatic, and draw spells to get deadly on as much as you can and go wild. I've beaten reanimator several times by holding back several deadly BSHs for each reanimation. Lost too, but that's how you go when you pit combo vs combo. Some cards I'm still unsure of the exact amount, so I'd be more than happy to get suggestions for fine tuning, but the bottom line is that this deck is fun.
The sideboard holds some cards I've though of for the market. Alpine Tracker could be maindecked, but considering with deadly he'd be a "leave a witness", not sure we want him as we often have more creatures on board.
Hope you have a blast!
