There's no shortage of zombie decks out there, but I think a Jund zombie deck is on the rarer side. How did we come up with this one? Fast zombies! All those other Commander decks are filled with those regular old slow zombies, but this deck is all about the fast ones. They probably scream instead of moan also.
Most of our zombies come from non-creature cards that generate zombie tokens, and the few actual creature cards we run are all about giving our tokens haste, granting us extra combat steps, and antheming them up by +1/+1 or more. The green is for mass pump and sacking tokens to turn them into those support creature cards. And the Commander? Thantis, the Warweaver. Having our opponents attack all the time is a great way to clear the way for our army to run through and dominate.
