The basis for this deck already existed.
There’s even more options, like Reassembling Skeleton, but I don’t think we want to use the mana on a 1/1. Maybe, though.
The mana is pretty good, but painful. Also, sometimes you’ll just sit there playing tapped lands. Still, it’s hard to do much about that, since you basically need the turn 1 of any mana, which is sadly not going to happen as often as one would like.
You could lose a few red sources, if you also gave up the Grim Initiate, so that’s something one should think about.
