I was planning on making a {B}{G} graveyard deck EDH with him as the commander. I'mma call the deck "Sacrificial Rites"
I like him. Really good sac outlet that gets bigger as you sac stuff? Yes please. And it's easy to get him back. Stuff I'd recommend:
{Buried Alive}
{Living End} could win you games. Easy.
{Living Death} because one living end isn't enough
Also dredge stuff.
{Dakmor Salvage}
{Grave-Shell Scarab}
{Life from the Loam}
Jarad's an awesome commander! Give it a shot. He's powerful yet not one of those ones that make you a public enemy from the start. Good luck!
Huge combo commander
Make sure you have {Grave Pact} {Greater Good}
Sadness all day
{Reaper from the abyss}
{Magus of the abyss}
{The Abyss}
{Bitterblossom}
{Something the walking grave}
{maelstrom pulse}
{abrupt decay}
{spiritmonger}
{Jarad, Golgari Lich Lord}
{crucible of worlds}.
&$!@ yea he is!
{Svogthos, the Restless Tomb}
Yez. I use all of those.
{Altar's Reap}, and the new Waste Not when it comes out.
